public final Boolean enabled()

When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

Default: True

Returns:

When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

Default: True

batchSize

public final Integer batchSize()

The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

• Amazon Kinesis – Default 100. Max 10,000.

• Amazon DynamoDB Streams – Default 100. Max 10,000.

• Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

• Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.

• Self-managed Apache Kafka – Default 100. Max 10,000.

• Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.

Returns:

The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

• Amazon Kinesis – Default 100. Max 10,000.

• Amazon DynamoDB Streams – Default 100. Max 10,000.

• Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

• Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.

• Self-managed Apache Kafka – Default 100. Max 10,000.

• Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.

filterCriteria

public final FilterCriteria filterCriteria()

An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

Returns:

An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

maximumBatchingWindowInSeconds

public final Integer maximumBatchingWindowInSeconds()

The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

Returns:

The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms.

Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

destinationConfig

public final DestinationConfig destinationConfig()

(Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.

Returns:

(Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.

maximumRecordAgeInSeconds

public final Integer maximumRecordAgeInSeconds()

(Streams only) Discard records older than the specified age. The default value is infinite (-1).

Returns:

(Streams only) Discard records older than the specified age. The default value is infinite (-1).

bisectBatchOnFunctionError

public final Boolean bisectBatchOnFunctionError()

(Streams only) If the function returns an error, split the batch in two and retry.

Returns:

(Streams only) If the function returns an error, split the batch in two and retry.

maximumRetryAttempts

public final Integer maximumRetryAttempts()

(Streams only) Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

Returns:

(Streams only) Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

parallelizationFactor

public final Integer parallelizationFactor()

(Streams only) The number of batches to process from each shard concurrently.

Returns:

(Streams only) The number of batches to process from each shard concurrently.

hasSourceAccessConfigurations

public final boolean hasSourceAccessConfigurations()

For responses, this returns true if the service returned a value for the SourceAccessConfigurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

sourceAccessConfigurations

public final List<SourceAccessConfiguration> sourceAccessConfigurations()

An array of authentication protocols or VPC components required to secure your event source.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSourceAccessConfigurations() method.

Returns:

An array of authentication protocols or VPC components required to secure your event source.

tumblingWindowInSeconds

public final Integer tumblingWindowInSeconds()

(Streams only) The duration in seconds of a processing window. The range is between 1 second and 900 seconds.

Returns:

(Streams only) The duration in seconds of a processing window. The range is between 1 second and 900 seconds.

functionResponseTypes

public final List<FunctionResponseType> functionResponseTypes()

(Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFunctionResponseTypes() method.

Returns:

(Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.

hasFunctionResponseTypes

public final boolean hasFunctionResponseTypes()

For responses, this returns true if the service returned a value for the FunctionResponseTypes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

functionResponseTypesAsStrings

public final List<String> functionResponseTypesAsStrings()

(Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFunctionResponseTypes() method.

Returns:

(Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.

scalingConfig

public final ScalingConfig scalingConfig()

(Amazon SQS only) The scaling configuration for the event source. For more information, see Configuring maximum concurrency for Amazon SQS event sources.
