 The parameter specifies the time duration during which bucket entries are accepted for processing.

+When defined, bucket entries are processed only if their last modified timestamp falls within the specified time duration, relative to the current time.
 However, when the start_timestamp is set, the initial processing will include all bucket entries up to that timestamp.

+NOTE: Bucket entries that are older than the defined duration and have failed processing will not be re-processed.

 Additionally, this ensures that subsequent runs can include and re-process objects that failed due to unavoidable errors.

 This parameter is useful when configuring input for the first time, especially if you want to ingest logs starting from a specific time.
 The timestamp can also be set to a future time, offering greater flexibility.
+You can combine this property with ignore_older duration to improve memory usage by reducing tracked bucket entries.
