Mar 21, 2012 · HBase supports ACID in limited ways, namely Puts to the same row provide all ACID guarantees. (HBASE-3584 adds multi op transactions and HBASE-5229 adds multi row transactions, but the principle remains the same) So how does ACID work in HBase? HBase employs a kind of MVCC. And HBase has no mixed read/write transactions.Author: Lars Hofhansl

“transactional support” and “SQL interface”. Transactions are designed to maintain database integrity in a known, consistent state, by ensuring that interdependent operations on the system complete successfully or all the operations are canceled. This paper describes a non-intrusive approach to provide transaction support for HBase
