Hive ACID Transactions

Qubole supports ACID transactions from Hive 3.1.1 (beta) and it has optimized open-source Hive ACID transactions. Hive ACID transactions enable atomicity of operations at the row level, which allows a Hive client to read from a partition or table and simultaneously, another Hive client can add rows to the same partition or table. It also brings with it the support for commands such as UPDATE, DELETE and MERGE, and enables corresponding use cases in an efficient and cost-effective manner.
