How parallel query will be benifited by big table cahe feature of 12c

edited Nov 22, 2017 2:54PM in Database DataWarehousing (MOSC) 5 commentsAnswered

Hello expert,

                     Recently big table cache feature of 12c drew my attention but I am wondering how this will be benefitted for large parallel query using full table scan?As far as I know full table scan by parallel query bypass buffer cache and loads data directly into PGA using temporary tablespace.If that is the case then this feature can not be used for large datawarehouse system.

Expecting expert advise/suggestion.
