Sait Talha Nisanci	44953579cf	Enable citus-local distributed table joins ... Check equality in quals We want to recursively plan distributed tables only if they have an equality filter on a unique column. So '>' and '<' operators will not trigger recursive planning of distributed tables in local-distributed table joins. Recursively plan distributed table only if the filter is constant If the filter is not a constant then the join might return multiple rows and there is a chance that the distributed table will return huge data. Hence if the filter is not constant we choose to recursively plan the local table.	2020-12-15 18:17:10 +03:00
Sait Talha Nisanci	f3d55448b3	Choose distributed table if it has a unique index in filter ... When doing local-distributed table joins we convert one of them to subquery. The current policy is that we convert distributed tables to subquery if it has a unique index on a column that has unique index(primary key also has a unique index).	2020-12-15 18:17:10 +03:00
