Returns the factory that can parse this type (that is, type CO).
Typically, implementations of this method should return the companion object of the implementing class. The companion object in turn should implement FromConfigFactory.

Spark SQL condition evaluated as where-clause against dataframe of metrics.
Spark SQL condition evaluated as where-clause against dataframe of metrics. Available columns are dataObjectId, key, value. If there are any rows passing the where clause, a MetricCheckFailed exception is thrown.

Initialize Action with SubFeed's to be processed. In this step the execution mode is evaluated and the result stored for the exec phase. If successful - the DAG can be built - Spark DataFrame lineage can be built

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 to cleanup after executing an action failed.

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 Action init is skipped if result is false.
Checks before initalization of Action In this step execution condition is evaluated and 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.
Implement additional preprocess logic for SubFeeds before transformation Can be implemented by subclass.

If filters should be ignored for this feed
If subfeed is recursive (input & output)
Recursive Inputs are DataObjects that are used as Output and Input in the same action.
Recursive Inputs are DataObjects that are used as Output and Input in the same action. This is usually prohibited as it creates loops in the DAG. In special cases this makes sense, i.e. when building a complex comparision/update logic.
Usage: add DataObjects used as Output and Input as outputIds and recursiveInputIds, but not as inputIds.
Sets the util job description for better traceability in the Spark UI
Sets the util job description for better traceability in the Spark UI
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.
