-------------------------------------
Summary: Add REGEXP_SPLIT function
Key: PHOENIX-1254
URL: https://issues.apache.org/jira/browse/PHOENIX-1254
Project: Phoenix
Issue Type: New Feature
Reporter: Gabriel Reid
Assignee: Gabriel Reid
It is really useful in some situations to have a string split function to split
string values into arrays of strings based on a delimiter string or pattern.
The intention is to add a REGEXP_SPLIT function that works in similar fashion
to the [Postgresql REGEXP_SPLIT_TO_ARRAY
function|http://www.postgresql.org/docs/9.1/static/functions-string.html].
The function will take two parameters:
* the input value to be split
* the regular expression pattern to be used to split the input into an array
The output of the function will be {{VARCHAR_ARRAY}}
