It was obviously relevant for our internal developers, so he unhesistantly granted me permission to reproduce some of his ideas for us. Cary, thank you very much!

Oracle 12c InMemory – don’t stop thinking about performance

Oracle has released its new database version 12.1.0.2 that includes the famous in-memory column store. InMemory option  promises a big advantage for OLAP-like work loads by keeping table contents in a columnar in-memory structure.
