Apache Phoenix is an open source , massively parallel , relational database engine supporting OLTP for Hadoop using Apache HBase as its backing store. Phoenix provides a JDBC driver that hides the intricacies of the noSQL store enabling users to create, delete, and alter SQL tables, views, indexes, and sequences; Insert and delete rows singly and in bulk; And query data through SQL .  Phoenix compiles queries and other statements in native noSQL store APIs rather than using MapReduceenabling the building of low latency applications on top of noSQL stores. 
Phoenix Began as an internal project by the company salesforce.com out of a need to support has Higher Level, well Understood, SQL language. Originally It was open-sourced it GitHub  and est devenu a top-level Apache project is 22 May 2014.  Apache Phoenix is included in the Hortonworks distribution for HDP 2.1 and above,  is available as share of Cloudera Labs,  and is part of the Hadoop ecosystem.
