"Sleeper Features" would be an awesome article for the NoCOUG Journal if you would write one for us. My pet "sleeper feature" is the oldest in the book: multi-table clusters in indexed and hash flavors. Even Oracle product management does not believe in it. Partitioned hash clusters were first used by Oracle in TPC-C benchmarks more than two years but have not been implemented in Oracle Database 12c. See http://iggyfernandez.wordpress.com/2011/05/10/major-new-undocumented-partitioning-feature-in-oracle-database-11g-release-2/. I believe that clusters hold the answers to many performance problems as well as the antidote to NoSQL. See http://iggyfernandez.wordpress.com/2013/07/28/no-to-sql-and-no-to-nosql/. How about MDC (Multidimensional clustering)? Clusters again! See http://iggyfernandez.wordpress.com/2011/03/26/multidimensional-clustering-mdc-in-oracle-database/. Another sleeper feature!
