Subject [jira] [Commented] (PHOENIX-1660) Implement missing math built-in functions
Date Sun, 15 Mar 2015 13:08:38 GMT


Rishal Shah commented on PHOENIX-1660:

I am Rishal Shah, an engineering student from Mumbai, India. I am interested in contributing
to this issue as a project in GSOC for this year.

I have gone through the links that are given in the project description. I have also read
how to implement new functions using JAVA code link. I am well versed with coding in JAVA
and also in handling Databases. I would like to build new functions for Phoenix and contribute
to this project in whichever way possible.

So can someone help me with the minimum requirements for this project. Waiting for a positive
reply soon.

> Take a look at the typical math functions that are implemented in relational database
systems ( and implement
the same for Phoenix in Java following this guide:
> 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.
