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 `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.

The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.The minimum valid value for maximum record age is 60s. Although values less than 60 and greater than -1 fall within the parameter's absolute range, they are not allowed

## `maximum_retry_attempts`{% #maximum_retry_attempts %}

**Type**: `INT32`**Provider name**: `MaximumRetryAttempts`**Description**: (Kinesis and DynamoDB Streams only) Discard records after the specified number of retries.
