[ANNOUNCE] Phoenix v 2.1 released
The Phoenix team is pleased to announce the immediate availability of
Phoenix 2.1 [1].
More than 20 individuals contributed to the release. Here are some of the
new features
now available:
* Secondary Indexing [2] to create and automatically maintain global
indexes over your
   primary table.
   - Queries automatically use an index when more efficient, turning your
full table scans
     into point and range scans.
   - Multiple columns may be indexed in ascending or descending sort order.
   - Additional primary table columns may be included in the index to form
a covered
   - Available in two flavors:
        o Server-side index maintenance for mutable data.
        o Client-side index maintenance optimized for write-once,
append-only use cases.
* Row Value Constructors [3], a standard SQL construct to efficiently
locate the row at
  or after a composite key value.
   - Enables a query-more capability to efficiently step through your data.
   - Optimizes IN list of composite key values to be point gets.
* Map-reduce based CSV Bulk Loader [4] to build Phoenix-compliant HFiles
and load
  them into HBase.
* MD5 hash and INVERT built-in functions

Phoenix 2.1 requires HBase 0.94.4 or above, with 0.94.10 or above required
for mutable secondary indexing. For the best performance, we recommend
HBase 0.94.12 or above.
