Does rapids support CBO optimization ?[QST]

[chenrui17]

like cpu spark , we can set spark.sql.cbo.enabled true ,and spark.sql.cbo.joinReorder.enabled true to Adjust the order of the join.if i set this config on rapids, can it work ?

The rapids accelerator operates at the level of the physical plan. The CBO works at the level of the logical plan so it should work out of the box. We have not tested this yet. If you run into issues please let us know.
