Execution Payload Retention
In addition to CloudWatch logs and AWS StepFunction API records, Cumulus automatically stores the initial and 'final' (the last update to the execution record) payload values as part of the Execution record in your RDS database and Elasticsearch.
This allows access via the API (or optionally direct DB/Elasticsearch querying) for debugging/reporting purposes. The data is stored in the "originalPayload" and "finalPayload" fields.
Payload record cleanup
To reduce storage requirements, a CloudWatch rule ({stack-name}-dailyExecutionPayloadCleanupRule) triggering a daily run of the provided cleanExecutions lambda has been added. This lambda will remove all 'completed' and 'non-completed' payload records in the database that are older than the specified configuration.
Configuration
The following configuration flags have been made available in the cumulus module. They may be overridden in your deployment's instance of the cumulus module by adding the following configuration options:
dailyexecution_payload_cleanup_schedule_expression (string)_
This configuration option sets the execution times for this Lambda to run, using a Cloudwatch cron expression.
Default value is "cron(0 4 * * ? *)".
completeexecution_payload_timeout_disable (bool)_
This configuration option, when set to true, will disable all cleanup of completed execution payloads.
Default value is false.
completeexecution_payload_timeout (number)_
This flag defines the cleanup threshold for executions with a 'completed' status in days. Records with updatedAt values older than this with payload information will have that information removed.
Default value is 10.
noncomplete_execution_payload_timeout_disable (bool)_
This configuration option, when set to true, will disable all cleanup of "non-complete" (any status other than completed) execution payloads.
Default value is false.
noncomplete_execution_payload_timeout (number)_
This flag defines the cleanup threshold for executions with a status other than 'complete' in days. Records with updateTime values older than this with payload information will have that information removed.
Default value is 30 days.
- complete_execution_payload_disable/non_complete_execution_payload_disable
These flags (true/false) determine if the cleanup script's logic for 'complete' and 'non-complete' executions will run. Default value is false for both.
