public void setEndpoint(String endpoint)
AmazonKinesis
Callers can pass in just the endpoint (ex: "kinesis.us-east-1.amazonaws.com") or a full URL, including the
protocol (ex: "https://kinesis.us-east-1.amazonaws.com"). If the protocol is not specified here, the default
protocol from this client's ClientConfiguration
will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

public AddTagsToStreamResult addTagsToStream(AddTagsToStreamRequest request)
AmazonKinesis
Adds or updates tags for the specified Kinesis data stream. You can assign up to 50 tags to a data stream.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
If tags have already been assigned to the stream, AddTagsToStream
overwrites any existing tags that
correspond to the specified tag keys.
AddTagsToStream has a limit of five transactions per second per account.
addTagsToStream

.public CreateStreamResult createStream(CreateStreamRequest request)
AmazonKinesis
Creates a Kinesis data stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream.
You can create your data stream using either on-demand or provisioned capacity mode. Data streams with an on-demand mode require no capacity planning and automatically scale to handle gigabytes of write and read throughput per minute. With the on-demand mode, Kinesis Data Streams automatically manages the shards in order to provide the necessary throughput. For the data streams with a provisioned mode, you must specify the number of shards for the data stream. Each shard can support reads up to five transactions per second, up to a maximum data read total of 2 MiB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MiB per second. If the amount of data input increases or decreases, you can add or remove shards.
The stream name identifies the stream. The name is scoped to the Amazon Web Services account used by the application. It is also scoped by Amazon Web Services Region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different Regions, can have the same name.
CreateStream
is an asynchronous operation. Upon receiving a CreateStream
request,
Kinesis Data Streams immediately returns and sets the stream status to CREATING
. After the stream is
created, Kinesis Data Streams sets the stream status to ACTIVE
. You should perform read and write
operations only on an ACTIVE
stream.
You receive a LimitExceededException
when making a CreateStream
request when you try to
do one of the following:
Have more than five streams in the CREATING
state at any point in time.
Create more shards than are authorized for your account.
For the default shard limit for an Amazon Web Services account, see Amazon Kinesis Data Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact Amazon Web Services Support.
You can use DescribeStreamSummary to check the stream status, which is returned in
StreamStatus
.
CreateStream has a limit of five transactions per second per account.

public DecreaseStreamRetentionPeriodResult decreaseStreamRetentionPeriod(DecreaseStreamRetentionPeriodRequest request)
AmazonKinesis
Decreases the Kinesis data stream's retention period, which is the length of time data records are accessible after they are added to the stream. The minimum value of a stream's retention period is 24 hours.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
This operation may result in lost data. For example, if the stream's retention period is 48 hours and is decreased to 24 hours, any data already in the stream that is older than 24 hours is inaccessible.
decreaseStreamRetentionPeriod
in interface AmazonKinesis
request
- Represents the input for DecreaseStreamRetentionPeriod.public DeleteStreamResult deleteStream(DeleteStreamRequest request)
AmazonKinesis
Deletes a Kinesis data stream and all its shards and data. You must shut down any applications that are operating
on the stream before you delete the stream. If an application attempts to operate on a deleted stream, it
receives the exception ResourceNotFoundException
.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
If the stream is in the ACTIVE
state, you can delete it. After a DeleteStream
request,
the specified stream is in the DELETING
state until Kinesis Data Streams completes the deletion.
Note: Kinesis Data Streams might continue to accept data read and write operations, such as
PutRecord, PutRecords, and GetRecords, on a stream in the DELETING
state until
the stream deletion is complete.
When you delete a stream, any shards in that stream are also deleted, and any tags are dissociated from the stream.
You can use the DescribeStreamSummary operation to check the state of the stream, which is returned in
StreamStatus
.
DeleteStream has a limit of five transactions per second per account.

public DeregisterStreamConsumerResult deregisterStreamConsumer(DeregisterStreamConsumerRequest request)
AmazonKinesis
To deregister a consumer, provide its ARN. Alternatively, you can provide the ARN of the data stream and the name you gave the consumer when you registered it. You may also provide all three parameters, as long as they don't conflict with each other. If you don't know the name or ARN of the consumer that you want to deregister, you can use the ListStreamConsumers operation to get a list of the descriptions of all the consumers that are currently registered with a given data stream. The description of a consumer contains its name and ARN.
This operation has a limit of five transactions per second per stream.
deregisterStreamConsumer
in interface AmazonKinesis
public DescribeLimitsResult describeLimits(DescribeLimitsRequest request)
AmazonKinesis
Describes the shard limits and usage for the account.
If you update your account limits, the old limits might be returned for a few minutes.
This operation has a limit of one transaction per second per account.
describeLimits
in interface AmazonKinesis
public DescribeStreamResult describeStream(DescribeStreamRequest request)
AmazonKinesis
Describes the specified Kinesis data stream.
This API has been revised. It's highly recommended that you use the DescribeStreamSummary API to get a summarized description of the specified Kinesis data stream and the ListShards API to list the shards in a specified data stream and obtain information about each shard.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
The information returned includes the stream name, Amazon Resource Name (ARN), creation time, enhanced metric configuration, and shard map. The shard map is an array of shard objects. For each shard object, there is the hash key and sequence number ranges that the shard spans, and the IDs of any earlier shards that played in a role in creating the shard. Every record ingested in the stream is identified by a sequence number, which is assigned when the record is put into the stream.
You can limit the number of shards returned by each call. For more information, see Retrieving Shards from a Stream in the Amazon Kinesis Data Streams Developer Guide.
There are no guarantees about the chronological order shards returned. To process shards in chronological order, use the ID of the parent shard to track the lineage to the oldest shard.
This operation has a limit of 10 transactions per second per account.

StreamName
input parameter.
enableEnhancedMonitoring
in interface AmazonKinesis
request
- Represents the input for EnableEnhancedMonitoring.public GetRecordsResult getRecords(GetRecordsRequest request)
AmazonKinesis
Gets data records from a Kinesis data stream's shard.
When invoking this API, it is recommended you use the StreamARN
input parameter in addition to the
ShardIterator
parameter.
Specify a shard iterator using the ShardIterator
parameter. The shard iterator specifies the
position in the shard from which you want to start reading data records sequentially. If there are no records
available in the portion of the shard that the iterator points to, GetRecords returns an empty list. It
might take multiple calls to get to a portion of the shard that contains records.
You can scale by provisioning multiple shards per stream while considering service limits (for more information,
see Amazon Kinesis Data
Streams Limits in the Amazon Kinesis Data Streams Developer Guide). Your application should have one
thread per shard, each reading continuously from its stream. To read from a stream continually, call
GetRecords in a loop. Use GetShardIterator to get the shard iterator to specify in the first
GetRecords call. GetRecords returns a new shard iterator in NextShardIterator
. Specify
the shard iterator returned in NextShardIterator
in subsequent calls to GetRecords. If the
shard has been closed, the shard iterator can't return more data and GetRecords returns null
in NextShardIterator
. You can terminate the loop when the shard is closed, or when the shard
iterator reaches the record with the sequence number or other attribute that marks it as the last record to
process.
Each data record can be up to 1 MiB in size, and each shard can read up to 2 MiB per second. You can ensure that
your calls don't exceed the maximum supported size or throughput by using the Limit
parameter to
specify the maximum number of records that GetRecords can return. Consider your average record size when
determining this limit. The maximum number of records that can be returned per call is 10,000.
The size of the data returned by GetRecords varies depending on the utilization of the shard. It is
recommended that consumer applications retrieve records via the GetRecords
command using the 5 TPS
limit to remain caught up. Retrieving records less frequently can lead to consumer applications falling behind.
The maximum size of data that GetRecords can return is 10 MiB. If a call returns this amount of data,
subsequent calls made within the next 5 seconds throw ProvisionedThroughputExceededException
. If
there is insufficient provisioned throughput on the stream, subsequent calls made within the next 1 second throw
ProvisionedThroughputExceededException
. GetRecords doesn't return any data when it throws an
exception. For this reason, we recommend that you wait 1 second between calls to GetRecords. However, it's
possible that the application will get exceptions for longer than 1 second.
To detect whether the application is falling behind in processing, you can use the
MillisBehindLatest
response attribute. You can also monitor the stream using CloudWatch metrics and
other mechanisms (see Monitoring in
the Amazon Kinesis Data Streams Developer Guide).
Each Amazon Kinesis record includes a value, ApproximateArrivalTimestamp
, that is set when a stream
successfully receives and stores a record. This is commonly referred to as a server-side time stamp, whereas a
client-side time stamp is set when a data producer creates or sends the record to a stream (a data producer is
any data source putting data records into a stream, for example with PutRecords). The time stamp has
millisecond precision. There are no guarantees about the time stamp accuracy, or that the time stamp is always
increasing. For example, records in a shard or across a stream might have time stamps that are out of order.
This operation has a limit of five transactions per second per shard.
getRecords
in interface AmazonKinesis
request
- Represents the input for GetRecords.public GetShardIteratorResult getShardIterator(GetShardIteratorRequest request)
AmazonKinesis
Gets an Amazon Kinesis shard iterator. A shard iterator expires 5 minutes after it is returned to the requester.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
A shard iterator specifies the shard position from which to start reading data records sequentially. The position is specified using the sequence number of a data record in a shard. A sequence number is the identifier associated with every record ingested in the stream, and is assigned when a record is put into the stream. Each stream has one or more shards.
You must specify the shard iterator type. For example, you can set the ShardIteratorType
parameter
to read exactly from the position denoted by a specific sequence number by using the
AT_SEQUENCE_NUMBER
shard iterator type. Alternatively, the parameter can read right after the
sequence number by using the AFTER_SEQUENCE_NUMBER
shard iterator type, using sequence numbers
returned by earlier calls to PutRecord, PutRecords, GetRecords, or DescribeStream. In
the request, you can specify the shard iterator type AT_TIMESTAMP
to read records from an arbitrary
point in time, TRIM_HORIZON
to cause ShardIterator
to point to the last untrimmed
record in the shard in the system (the oldest data record in the shard), or LATEST
so that you
always read the most recent data in the shard.
When you read repeatedly from a stream, use a GetShardIterator request to get the first shard iterator for
use in your first GetRecords request and for subsequent reads use the shard iterator returned by the
GetRecords request in NextShardIterator
. A new shard iterator is returned by every
GetRecords request in NextShardIterator
, which you use in the ShardIterator
parameter of the next GetRecords request.
If a GetShardIterator request is made too often, you receive a
ProvisionedThroughputExceededException
. For more information about throughput limits, see
GetRecords, and Streams Limits in the
Amazon Kinesis Data Streams Developer Guide.
If the shard is closed, GetShardIterator returns a valid iterator for the last sequence number of the shard. A shard can be closed as a result of using SplitShard or MergeShards.
GetShardIterator has a limit of five transactions per second per account per open shard.

public IncreaseStreamRetentionPeriodResult increaseStreamRetentionPeriod(IncreaseStreamRetentionPeriodRequest request)
AmazonKinesis
Increases the Kinesis data stream's retention period, which is the length of time data records are accessible after they are added to the stream. The maximum value of a stream's retention period is 8760 hours (365 days).
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
If you choose a longer stream retention period, this operation increases the time period during which records that have not yet expired are accessible. However, it does not make previous, expired data (older than the stream's previous retention period) accessible after the operation has been called. For example, if a stream's retention period is set to 24 hours and is increased to 168 hours, any data that is older than 24 hours remains inaccessible to consumer applications.

When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
This action does not list expired shards. For information about expired shards, see Data Routing, Data Persistence, and Shard State after a Reshard.
This API is a new operation that is used by the Amazon Kinesis Client Library (KCL). If you have a fine-grained IAM policy that only allows specific operations, you must update your policy to allow calls to this API. For more information, see Controlling Access to Amazon Kinesis Data Streams Resources Using IAM.

public ListStreamsResult listStreams(ListStreamsRequest request)
AmazonKinesis
Lists your Kinesis data streams.
The number of streams may be too large to return from a single call to ListStreams
. You can limit
the number of returned streams using the Limit
parameter. If you do not specify a value for the
Limit
parameter, Kinesis Data Streams uses the default limit, which is currently 100.
You can detect if there are more streams available to list by using the HasMoreStreams
flag from the
returned output. If there are more streams available, you can request more streams by using the name of the last
stream returned by the ListStreams
request in the ExclusiveStartStreamName
parameter in
a subsequent request to ListStreams
. The group of stream names returned by the subsequent request is
then added to the list. You can continue this process until all the stream names have been collected in the list.
ListStreams has a limit of five transactions per second per account.

.public MergeShardsResult mergeShards(MergeShardsRequest request)
AmazonKinesis
Merges two adjacent shards in a Kinesis data stream and combines them into a single shard to reduce the stream's capacity to ingest and transport data. This API is only supported for the data streams with the provisioned capacity mode. Two shards are considered adjacent if the union of the hash key ranges for the two shards form a contiguous set with no gaps. For example, if you have two shards, one with a hash key range of 276...381 and the other with a hash key range of 382...454, then you could merge these two shards into a single shard that would have a hash key range of 276...454. After the merge, the single child shard receives data for all hash key values covered by the two parent shards.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
MergeShards
is called when there is a need to reduce the overall capacity of a stream because of
excess capacity that is not being used. You must specify the shard to be merged and the adjacent shard for a
stream. For more information about merging shards, see Merge Two
Shards in the Amazon Kinesis Data Streams Developer Guide.
If the stream is in the ACTIVE
state, you can call MergeShards
. If a stream is in the
CREATING
, UPDATING
, or DELETING
state, MergeShards
returns a
ResourceInUseException
. If the specified stream does not exist, MergeShards
returns a
ResourceNotFoundException
.
You can use DescribeStreamSummary to check the state of the stream, which is returned in
StreamStatus
.
MergeShards
is an asynchronous operation. Upon receiving a MergeShards
request, Amazon
Kinesis Data Streams immediately returns a response and sets the StreamStatus
to
UPDATING
. After the operation is completed, Kinesis Data Streams sets the StreamStatus
to ACTIVE
. Read and write operations continue to work while the stream is in the
UPDATING
state.
You use DescribeStreamSummary and the ListShards APIs to determine the shard IDs that are specified
in the MergeShards
request.
If you try to operate on too many streams in parallel using CreateStream, DeleteStream,
MergeShards
, or SplitShard, you receive a LimitExceededException
.
MergeShards
has a limit of five transactions per second per account.

public PutRecordResult putRecord(PutRecordRequest request)
AmazonKinesis
Writes a single data record into an Amazon Kinesis data stream. Call PutRecord
to send data into the
stream for real-time ingestion and subsequent processing, one record at a time. Each shard can support writes up
to 1,000 records per second, up to a maximum data write total of 1 MiB per second.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams to distribute data across shards. Kinesis Data Streams segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine the shard to which a given data record belongs.
Partition keys are Unicode strings, with a maximum length limit of 256 characters for each key. An MD5 hash
function is used to map partition keys to 128-bit integer values and to map associated data records to shards
using the hash key ranges of the shards. You can override hashing the partition key to determine the shard by
explicitly specifying a hash value using the ExplicitHashKey
parameter. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
PutRecord
returns the shard ID of where the data record was placed and the sequence number that was
assigned to the data record.
Sequence numbers increase over time and are specific to a shard within a stream, not across all shards within a
stream. To guarantee strictly increasing ordering, write serially to a shard and use the
SequenceNumberForOrdering
parameter. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
After you write a record to a stream, you cannot modify that record or its order within the stream.
If a PutRecord
request cannot be processed because of insufficient provisioned throughput on the
shard involved in the request, PutRecord
throws ProvisionedThroughputExceededException
.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

public PutRecordsResult putRecords(PutRecordsRequest request)
AmazonKinesis
Writes multiple data records into a Kinesis data stream in a single call (also referred to as a
PutRecords
request). Use this operation to send data into the stream for data ingestion and
processing.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
Each PutRecords
request can support up to 500 records. Each record in the request can be as large as
1 MiB, up to a limit of 5 MiB for the entire request, including partition keys. Each shard can support writes up
to 1,000 records per second, up to a maximum data write total of 1 MiB per second.
You must specify the name of the stream that captures, stores, and transports the data; and an array of request
Records
, with each record in the array requiring a partition key and data blob. The record size
limit applies to the total size of the partition key and data blob.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams as input to a hash function that maps the partition key and associated data to a specific shard. An MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
Each record in the Records
array may include an optional parameter, ExplicitHashKey
,
which overrides the partition key to shard mapping. This parameter allows a data producer to determine explicitly
the shard where the record is stored. For more information, see Adding Multiple Records with PutRecords in the Amazon Kinesis Data Streams Developer Guide.
The PutRecords
response includes an array of response Records
. Each record in the
response array directly correlates with a record in the request array using natural ordering, from the top to the
bottom of the request and response. The response Records
array always includes the same number of
records as the request array.
The response Records
array includes both successfully and unsuccessfully processed records. Kinesis
Data Streams attempts to process all records in each PutRecords
request. A single record failure
does not stop the processing of subsequent records. As a result, PutRecords doesn't guarantee the ordering of
records. If you need to read records in the same order they are written to the stream, use PutRecord
instead of PutRecords
, and write to the same shard.
A successfully processed record includes ShardId
and SequenceNumber
values. The
ShardId
parameter identifies the shard in the stream where the record is stored. The
SequenceNumber
parameter is an identifier assigned to the put record, unique to all records in the
stream.
An unsuccessfully processed record includes ErrorCode
and ErrorMessage
values.
ErrorCode
reflects the type of error and can be one of the following values:
ProvisionedThroughputExceededException
or InternalFailure
. ErrorMessage
provides more detailed information about the ProvisionedThroughputExceededException
exception
including the account ID, stream name, and shard ID of the record that was throttled. For more information about
partially successful responses, see Adding Multiple Records with PutRecords in the Amazon Kinesis Data Streams Developer Guide.
After you write a record to a stream, you cannot modify that record or its order within the stream.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

- A PutRecords
request.public RegisterStreamConsumerResult registerStreamConsumer(RegisterStreamConsumerRequest request)
AmazonKinesis
Registers a consumer with a Kinesis data stream. When you use this operation, the consumer you register can then call SubscribeToShard to receive data from the stream using enhanced fan-out, at a rate of up to 2 MiB per second for every shard you subscribe to. This rate is unaffected by the total number of consumers that read from the same stream.
You can register up to 20 consumers per stream. A given consumer can only be registered with one stream at a time.
For an example of how to use this operations, see Enhanced Fan-Out Using the Kinesis Data Streams API.
The use of this operation has a limit of five transactions per second per account. Also, only 5 consumers can be
created simultaneously. In other words, you cannot have more than 5 consumers in a CREATING
status
at the same time. Registering a 6th consumer while there are 5 in a CREATING
status results in a
LimitExceededException
.

public RemoveTagsFromStreamResult removeTagsFromStream(RemoveTagsFromStreamRequest request)
AmazonKinesis
Removes tags from the specified Kinesis data stream. Removed tags are deleted and cannot be recovered after this operation successfully completes.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
If you specify a tag that does not exist, it is ignored.
RemoveTagsFromStream has a limit of five transactions per second per account.

.public SplitShardResult splitShard(SplitShardRequest request)
AmazonKinesis
Splits a shard into two new shards in the Kinesis data stream, to increase the stream's capacity to ingest and
transport data. SplitShard
is called when there is a need to increase the overall capacity of a
stream because of an expected increase in the volume of data records being ingested. This API is only supported
for the data streams with the provisioned capacity mode.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
You can also use SplitShard
when a shard appears to be approaching its maximum utilization; for
example, the producers sending data into the specific shard are suddenly sending more than previously
anticipated. You can also call SplitShard
to increase stream capacity, so that more Kinesis Data
Streams applications can simultaneously read data from the stream for real-time processing.
You must specify the shard to be split and the new hash key, which is the position in the shard where the shard gets split in two. In many cases, the new hash key might be the average of the beginning and ending hash key, but it can be any hash key value in the range being mapped into the shard. For more information, see Split a Shard in the Amazon Kinesis Data Streams Developer Guide.
You can use DescribeStreamSummary and the ListShards APIs to determine the shard ID and hash key
values for the ShardToSplit
and NewStartingHashKey
parameters that are specified in the
SplitShard
request.
SplitShard
is an asynchronous operation. Upon receiving a SplitShard
request, Kinesis
Data Streams immediately returns a response and sets the stream status to UPDATING
. After the
operation is completed, Kinesis Data Streams sets the stream status to ACTIVE
. Read and write
operations continue to work while the stream is in the UPDATING
state.
You can use DescribeStreamSummary to check the status of the stream, which is returned in
StreamStatus
. If the stream is in the ACTIVE
state, you can call
SplitShard
.
If the specified stream does not exist, DescribeStreamSummary returns a
ResourceNotFoundException
. If you try to create more shards than are authorized for your account,
you receive a LimitExceededException
.
For the default shard limit for an Amazon Web Services account, see Kinesis Data Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact Amazon Web Services Support.
If you try to operate on too many streams simultaneously using CreateStream, DeleteStream,
MergeShards, and/or SplitShard, you receive a LimitExceededException
.
SplitShard
has a limit of five transactions per second per account.

public StartStreamEncryptionResult startStreamEncryption(StartStreamEncryptionRequest request)
AmazonKinesis
Enables or updates server-side encryption using an Amazon Web Services KMS key for a specified stream.
Starting encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING
. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE
. Updating or applying encryption normally
takes a few seconds to complete, but it can take minutes. You can continue to read and write data to your stream
while its status is UPDATING
. Once the status of the stream is ACTIVE
, encryption
begins for records written to the stream.
API Limits: You can successfully apply a new Amazon Web Services KMS key for server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to 5 seconds after the stream is in an ACTIVE
status before all records written
to the stream are encrypted. After you enable encryption, you can verify that encryption is applied by inspecting
the API response from PutRecord
or PutRecords
.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.

AmazonKinesis
Disables server-side encryption for a specified stream.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
Stopping encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING
. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE
. Stopping encryption normally takes a few
seconds to complete, but it can take minutes. You can continue to read and write data to your stream while its
status is UPDATING
. Once the status of the stream is ACTIVE
, records written to the
stream are no longer encrypted by Kinesis Data Streams.
API Limits: You can successfully disable server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to 5 seconds after the stream is in an ACTIVE
status before all records written
to the stream are no longer subject to encryption. After you disabled encryption, you can verify that encryption
is not applied by inspecting the API response from PutRecord
or PutRecords
.

public UpdateShardCountResult updateShardCount(UpdateShardCountRequest request)
AmazonKinesis
Updates the shard count of the specified stream to the specified number of shards. This API is only supported for the data streams with the provisioned capacity mode.
When invoking this API, it is recommended you use the StreamARN
input parameter rather than the
StreamName
input parameter.
Updating the shard count is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING
. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE
. Depending on the size of the stream, the
scaling action could take a few minutes to complete. You can continue to read and write data to your stream while
its status is UPDATING
.
To update the shard count, Kinesis Data Streams performs splits or merges on individual shards. This can cause short-lived shards to be created, in addition to the final shards. These short-lived shards count towards your total shard limit for your account in the Region.
When using this operation, we recommend that you specify a target shard count that is a multiple of 25% (25%, 50%, 75%, 100%). You can specify any target value within your shard limit. However, if you specify a target that isn't a multiple of 25%, the scaling action might take longer to complete.
This operation has the following default limits. By default, you cannot do the following:
Scale more than ten times per rolling 24-hour period per stream
Scale up to more than double your current shard count for a stream
Scale down below half your current shard count for a stream
Scale up to more than 10000 shards in a stream
Scale a stream with more than 10000 shards down unless the result is less than 10000 shards
Scale up to more than the shard limit for your account
For the default limits for an Amazon Web Services account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To request an increase in the call rate limit, the shard limit for this API, or your overall shard limit, use the limits form.
