Aakarsh Agarwal commented on PHOENIX-1660:
------------------------------------------

Hello,
I am Aakarsh Agarwal, currently pursuing B.Tech from IIT Roorkee in India. I 
hope to participate in GSoC this year and want to contribute to this project. 
This project seems interesting to me because I feel comfortable in coding in 
JAVA, though I also know C++. 

I went through the links that are provided in the project description and it 
loooks interesting to build own functions and implement them for Phoenix. I am 
also going through its code on Github and lqatest commits to get more 
acquainted with the code.
I would like to hear from mentor how to get started and the probable challenges 
that needs to be fulfilled concering this project. I am eagerly waiting for a 
positive reply very soon.

Regards
AAKARSH AGARWAL

> 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.
