Hi, We have been running hive 1.2 successfully for few years. Hive-1.2 has been very stable for us.
We are planning to migrate to apache orc-1.5.12 thinking that we might get better performance. The plan is to keep hive-1.2 and replace orc with apache orc-1.5.12. We looked at the orc commit logs and didn't find much information on performance improvement. Would you mind sharing some of the performance improvements we might get after upgrading to orc-1.5.12 with hive-1.2? Thanks,
