EV SQL-2014 and vault stores maintenance plans-EV 12.1

I'm planning to create maintenance plan for enterprise vault 12.1 SQL vault store.
Does it negative impact for our environment if I re-indexing in SQL DBs in maintenance plan?
We are doing these tasks first time in Exchagne 2016 and ev archiving/ev journaling mailboxes and ev sql databases.
Please suggest.


Thanks-sami

Yes, you need to perform Index Rebuild/Reorganize for better performance.

Hi Raja,

Can rebuilding indexes cause worse performance after rebuild is finished for EV SQL Databases?

Thanks-Sami

Nope, ideally Index Rebuild will help in better performance by creating an optimal execution plan.
However there is a catch that the first time execution of queries referring to the rebuilt indexes will force the creation of a new execution plan which can take a little bit longer but it would be insignificant compared to the query running with heavily fragmented indexes.
