Purpose

Starting in Oracle Database 12c Release 2 (12.2), ADO manages the In-Memory (IM)  column store as a new data tier.   You can create policies to evict objects from the IM column store when they degrade performance, and populate objects when they improve performance. ADO manages the IM column store using Heat Map statistics.

Scope

 Automatic Data Optimization policies can now automatically populate or remove objects from the In-memory Column Store, based on their access/usage.
