--------------------------------------

Hi [~namit]

I have a rebased patch on trunk. I was trying to produce a test using the tables available
in the unit tests. Can I use the test you have provided in this jira?

Thanks
Vikram.

> If tables are just bucketed but not sorted, we are generating smb join operator. This
results in loss of rows in queries.
