Many thanks for this announcement.

This is a question that I have been seeking verification.

Does the new release of 4.9.0 of Phoenix support transactional and ACID compliance on Hbase? In a naïve way can one do what an RDBMS does with a combination of Hbase + Phoenix!

FYI, I am not interested on add-ons or some beta test tools such as Phoenix with combination of some other product.
