------------------------------------
Summary: Support UNNEST for ARRAY
Key: PHOENIX-953
URL: https://issues.apache.org/jira/browse/PHOENIX-953
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
The UNNEST built-in function converts an array into a set of rows. For an
example, see the following Postgres documentation:
http://www.postgresql.org/docs/8.4/static/functions-array.html
http://www.anicehumble.com/2011/07/postgresql-unnest-function-do-many.html
http://tech.valgog.com/2010/05/merging-and-manipulating-arrays-in.html
So the UNNEST is a way of converting an array to a flattened "table" which can
then be filtered on, ordered, grouped, etc.
