Hi [~tejasp] [~chengsu]
How to join two bucketed tables, when tables are bucketed on multiple columns.
I tried to join, but still exchanges were getting created.
Below is the scenario:
table1 bucketed by a 10 buckets
table2 bucketed by a,b 10 bucktes
how to join table1 and table2 on column a without exchanges?
