Planning to upgrade IQ 15.4 to IQ 16 .. Database size : 15 TB
Wanted to check . Is it mandatory rebuild index for wide columns .. ( Not sure how long rebuild will take ) ..
For rebuilding index for all wide columns in database . Can I run below command instead of running for individual table/column .
sp_iqrebuildindexwide [ table_name ] [, table_owner] [, level]
sp_iqrebuildindexwide NULL,NULL,1
So if I pass table_name and table_ower as NULL . Will it rebuild index for whole database for wide column .
Appreciate your suggestion .
Thanks
