mahesh kumar behera updated HIVE-23933:
---------------------------------------
Description: Current calcite 21 does not support getRowCountInt for anti
join.The selectivity calculation for anti join should be different than semi
join. It should be 1-semi join selectivity. (was: The current anti join
conversion does not support direct conversion of not-exists to anti join. The
not exists sub query is converted first to left out join and then its converted
to anti join. This may cause some of the optimization rule to be skipped.
)
> Add getRowCountInt support for anti join in calcite.
