BigZetta’s query accelerator, bzQAccel, acts as middleware between query processing and its execution on hardware (CPU+FPGA). bzQAccel has been architected to provide seamless integration with Hive and is agnostic of Hive version being used. User does not need to make any changes to either query code or cluster setup. In fact, the technology can be deployed on top of a running Hadoop cluster. Only change a user would see would be faster execution of queries.
