Stop propagating input FileRefs through action and instead get new FileRefs from DataObject according to the SubFeed's partitionValue.
Stop propagating input FileRefs through action and instead get new FileRefs from DataObject according to the SubFeed's partitionValue. This is needed to reprocess all files of a path/partition instead of the FileRef's passed from the previous Action.
If true delete files after they are successfully processed.

true if action should be executed. If false this only checks the prerequisits to do the processing and simulates the output FileRef's that would be created.

Runtime metrics
Runtime metrics
Note: runtime metrics are disabled by default, because they are only collected when running Actions from an ActionDAG. This is not the case for Tests or other use cases. If enabled exceptions are thrown if metrics are not found.

Executes operations needed after executing an action.
Executes operations needed after executing an action. In this step any task on Input- or Output-DataObjects needed after the main task is executed, e.g. JdbcTableDataObjects postWriteSql or CopyActions deleteInputData.
Executes operations needed before executing an action.
Executes operations needed before executing an action. In this step any phase on Input- or Output-DataObjects needed before the main task is executed, e.g. JdbcTableDataObjects preWriteSql
Checks before initalization of Action In this step execution condition is evaluated and is Action init is skipped if result is false.

Prepare DataObjects prerequisites.
Prepare DataObjects prerequisites. In this step preconditions are prepared & tested: - connections can be created - needed structures exist, e.g Kafka topic or Jdbc table
This runs during the "prepare" phase of the DAG.

Note: This sets Spark local properties, which are propagated to the respective executor tasks. We rely on this to match metrics back to Actions and DataObjects. As writing to a DataObject on the Driver happens uninterrupted in the same exclusive thread, this is suitable.
