[jira] [Updated] (PHOENIX-1516) Add RANDOM built-in function

["Lars Hofhansl (JIRA)" <ji...@apache.org>]

Lars Hofhansl updated PHOENIX-1516:
-----------------------------------
    Attachment: 1516.txt

Simple patch.

For discussion:
* is this enough? Should we allow setting the a random seed?
* do we need to generate the same random value for the same timestamp?
* with this it is impossible to generate a different random value for different column in the row (as the value will be same just one value per row), I can easily change that in the evaluate method, but how do we want it?

> I often find it useful to generate some rows with random data.
> Here's a simple RANDOM() function that we could use for that.
