Description: The Phoenix query engine translates SQL queries into one or more hbase scan and orchestrates execution to produce a standard JDBC result set. Directly using the HBase API, the co-processor and the custom filter, the performance magnitude is milliseconds for simple queries, and the performance magnitude is seconds for millions.
