MySQL Query Post-run Action

Runs a MySQL query at the end of the pipeline run. Can be configured to run only on success, only on failure, or always at the end of the run. For example, you might have a pipeline that imports data from a database table to HDFS files. At the end of the run, you might want to run a query that deletes the data that was read from the table.
