>> Phoenix is an open source SQL skin over HBase delivered as a
>> client-embedded JDBC driver targeting low latency queries over HBase data.
>> Phoenix takes your SQL query, compiles it into a series of HBase scans, and
>> orchestrates the running of those scans to produce regular JDBC result
>> sets. The table metadata is stored in an HBase table and versioned, such
>> that snapshot queries over prior versions will automatically use the

>> with both Pig and Map-reduce for the input and output of data.
>>
>> Background
>>
>> Phoenix initially started as an internal project at Salesforce.com to
>> efficiently analyze big data stored in HBase. It was open sourced on Github
>> about a year ago in Jan 2013. Over time Phoenix, together with HBase as the
>> storage tier, has begun to evolve into a general SQL database with support

>> multi-tenancy. This is expected to continue as Phoenix implements a
>> cost-based query optimizer and potentially transaction support, and
>> surfaces new HBase security features such as encryption and cell-level
>> security. Phoenix's developer community has also grown to include
>> additional companies such as Intel, who have contributed join support to
>> Phoenix, as well as Hortonworks, who are in the process of porting Phoenix
>> to the 0.96 release of HBase.

>>
>> Relationship with Other Apache Products
>>
>> Although Phoenix provides a higher level abstraction than Apache HBase by

>> test suite are run through Apache Maven.
>>
>> Phoenix offers an alternative query engine to Apache Hadoop (MapReduce).
>> Unlike MapReduce, Phoenix is designed for lower-latency, OLTP, and
>> interactive workloads. This makes the projects complimentary as users may
>> run MapReduce and Phoenix side-by-side.
