Hive development !

Hive 0.14 is now supporting ACID (atomicity, consistency, isolation and durability) transaction which lead to :

• UPDATE, DELETE
• BEGIN, COMMIT, ROLLBACK
• INSERT ... VALUES

Stinger.next will bring more SQL compliance (non-equi joins, more sub-queries, materialized views and others) and Apache Optiq is bringing cost-based optimization to improve performance.

This is really impressive !
