Deletes an event source mapping. You can get the identifier of a mapping from the output of ListEventSourceMappings.

When you delete an event source mapping, it enters a Deleting state and might not be completely deleted for several seconds.

delete/2015-03-31/event-source-mappings/{UUID}

Path parameters

UUIDstring required

The identifier of the event source mapping.

Response

Success

UUIDstring

The identifier of the event source mapping.

StartingPosition'TRIM_HORIZON' | 'LATEST' | 'AT_TIMESTAMP'

The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. <code>AT_TIMESTAMP</code> is supported only for Amazon Kinesis streams and Amazon DocumentDB.

StartingPositionTimestampstring date-time

With <code>StartingPosition</code> set to <code>AT_TIMESTAMP</code>, the time from which to start reading.

BatchSizeinteger
<p>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).</p> <p>Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.</p> <p>Related setting: When you set <code>BatchSize</code> to a value greater than 10, you must set <code>MaximumBatchingWindowInSeconds</code> to at least 1.</p>
MaximumBatchingWindowInSecondsinteger
<p>The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure <code>MaximumBatchingWindowInSeconds</code> to any value from 0 seconds to 300 seconds in increments of seconds.</p> <p>For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change <code>MaximumBatchingWindowInSeconds</code> 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.</p> <p>Related setting: For streams and Amazon SQS event sources, when you set <code>BatchSize</code> to a value greater than 10, you must set <code>MaximumBatchingWindowInSeconds</code> to at least 1.</p>
ParallelizationFactorinteger

(Kinesis and DynamoDB Streams only) The number of batches to process concurrently from each shard. The default value is 1.

EventSourceArnstring

The Amazon Resource Name (ARN) of the event source.

FunctionArnstring

The ARN of the Lambda function.

LastModifiedstring date-time

The date that the event source mapping was last updated or that its state changed.

LastProcessingResultstring

The result of the last Lambda invocation of your function.

Statestring

The state of the event source mapping. It can be one of the following: <code>Creating</code>, <code>Enabling</code>, <code>Enabled</code>, <code>Disabling</code>, <code>Disabled</code>, <code>Updating</code>, or <code>Deleting</code>.

StateTransitionReasonstring

Indicates whether a user or Lambda made the last change to the event source mapping.

TopicsTopic[]

The name of the Kafka topic.

QueuesQueue[]

(Amazon MQ) The name of the Amazon MQ broker destination queue to consume.

MaximumRecordAgeInSecondsinteger
<p>(Kinesis and DynamoDB Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.</p> <note> <p>The minimum value that can be set is 60 seconds.</p> </note>
BisectBatchOnFunctionErrorboolean

(Kinesis and DynamoDB Streams only) If the function returns an error, split the batch in two and retry. The default value is false.

MaximumRetryAttemptsinteger

(Kinesis and DynamoDB Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.

TumblingWindowInSecondsinteger

(Kinesis and DynamoDB Streams only) The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

FunctionResponseTypesFunctionResponseType[]

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