----------------------------------
Description:
Take a look at the typical date functions that are implemented in relational
database systems
(http://www.postgresql.org/docs/8.1/static/functions-datetime.html) and
implement the same for Phoenix in Java following this guide:
http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html
Examples of missing functions include EXTRACT, AGE, the INTERVAL operator, etc.

Take a look at the typical math functions that are implemented in relational
database systems
(http://www.postgresql.org/docs/current/static/functions-math.html) and
implement the same for Phoenix in Java following this guide:
http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html
Examples of missing functions include POWER, LOG, EXP, SQRT, CBRT, etc. As a
guide, examine how ROUND is implemented in Phoenix as an abstract function with
concrete functions per type: long, decimal, and date/time types.
