Subj: | | Re: Redestributing large tables instead of replicating a small table |
|
From: | | Praveen_Chakrapani |
Drop all the statistics (including index stats) on small table and check the explain. If it works as you expected then you can use this as a
temporary workaround. If stats are not collected then sometimes optimizer overestimates the rows in small table and goes for merge join by
duplicating small table. Give a try possibly it may work. If it works please post the results in the forum.
All the best :-)
Thanks,
Praveen
