-- MULTI_LARGE_TABLE_PLANNING
--
-- Tests that cover large table join planning. Note that we explicitly start a
-- transaction block here so that we don't emit debug messages with changing
-- transaction ids in them. Also, we set the executor type to task tracker
-- executor here, as we cannot run repartition jobs with real time executor.

-- Multi-level repartition join to verify our projection columns are correctly
-- referenced and propagated across multiple repartition jobs. The test also
-- validates that only the minimal necessary projection columns are transferred
-- between jobs.
