You could also explore the in-memory database of 12c . However, I am not sure how beneficial it is for Oltp scenarios.
I am excited to see how the performance will be on hbase as a hive metastore. Nevertheless, your results on Oracle/SSD will be beneficial for the community. > On 17 Apr 2016, at 11:52, Mich Talebzadeh <mich.talebza...@gmail.com> wrote: > > Hi, > > I have had my Hive metastore database on Oracle 11g supporting concurrency > (with added transactional capability) > > Over the past few days I created a new schema on Oracle 12c on Solid State > Disks (SSD) and used databump (exdp, imdp) to migrate Hive database from > Oracle 11g to Oracle 12c on SSD. > > Couple of years ago I did some work for OLTP operations (many random access > via index scan plus serial scans) for Oracle 11g and SAP ASE 15.7.
