We are pleased to announce the immediate availability of a new open 
source project, Phoenix, a SQL layer over HBase that powers the HBase 
use cases at Salesforce.com. We put the SQL back in the NoSQL:

  * Available on GitHub at https://github.com/forcedotcom/phoenix
  * Embedded JDBC driver implements the majority of java.sql interfaces,
    including the metadata APIs.
  * Built for low latency queries through parallelization, the use of
    native HBase APIs, coprocessors, and custom filters.
  * Allows columns to be modelled as a multi-part row key or key/value
    cells.
  * Full query support with predicate push down and optimal scan key
    formation.
  * DDL support: CREATE TABLE, DROP TABLE, and ALTER TABLE for
    adding/removing columns.
  * Versioned schema repository. Snapshot queries use the schema that
    was in place when data was written.
  * DML support: UPSERT VALUES for row-by-row insertion, UPSERT SELECT
    for mass data transfer between the same or different tables, and
    DELETE for deleting rows.
  * Limited transaction support through client-side batching.
  * Single table only - no joins yet and secondary indexes are a work in
    progress.
  * Follows ANSI SQL standards whenever possible
  * Requires HBase v 0.94.2 or above
  * BSD-like license
  * 100% Java
