public class PutRecordRequest extends AmazonWebServiceRequest implements Serializable
PutRecord operation
.
Puts a data record from a producer into an Amazon Kinesis stream. You
must call PutRecord
to send data from the producer into
the Amazon Kinesis stream for real-time ingestion and subsequent
processing. 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 could be a segment from a log file,
geographic/location data, website clickstream data, or any other data
type.
The partition key is used to distribute data across shards. Amazon Kinesis segregates the data records that belong to a data stream into multiple shards, using the partition key associated with each data record to determine which shard a given data record belongs to.
Partition keys are Unicode strings, with a maximum length limit of 256
bytes. 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
the
Amazon Kinesis 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 generally increase over time. To guarantee strictly
increasing ordering, use the SequenceNumberForOrdering
parameter. For more information, see the
Amazon Kinesis Developer Guide
.
If a PutRecord
request cannot be processed because of
insufficient provisioned throughput on the shard involved in the
request, PutRecord
throws
ProvisionedThroughputExceededException
.
Data records are accessible for only 24 hours from the time that they are added to an Amazon Kinesis stream.

partitionKey
- Determines which shard in the stream the data record is assigned to.
Partition keys are Unicode strings with a maximum length limit of 256
bytes. Amazon Kinesis uses the partition key as input to a hash
function that maps the partition key and associated data to a specific
shard. Specifically, 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 will map to the same shard within the stream.public PutRecordRequest withPartitionKey(String partitionKey)
