> Is the goal of this PR to replace & generalize this use case or the real issue you are trying to solve is something else ? Something completely different. Pre/postoperators in Vertica are SQL statements called before/after (Those are strings rather than callables) What this PR tries to achieve is to provide an option to override pre_/post_execute methods from the base operator with ones provided as constructor parameters. While it was already possible to override them by extending existing operators, it makes it a bit easier (and with less mental barriers for DAG writers) to provide such methods when you create task in DAG. While previously it required to create a new class and use the new class as operator, this on allows to create methods and pass them as parameters of the cosnstructor - which is easier for many users who write the DAGs. -- This is an automated message from the Apache Git Service.
