[jira] [Commented] (PHOENIX-1660) Implement missing math built-in
functions
[ https://issues.apache.org/jira/browse/PHOENIX-1660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14327093#comment-14327093 ]
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

> Key: PHOENIX-1660
> URL: https://issues.apache.org/jira/browse/PHOENIX-1660
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Labels: Java, SQL, gsoc2015, mentor
>
> 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.
