> Implement built-in functions for JSON
> -------------------------------------

> Key: PHOENIX-1661
> URL: https://issues.apache.org/jira/browse/PHOENIX-1661
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Labels: JSON, Java, SQL, gsoc2015, mentor
> Attachments: PhoenixJSONSpecification-First-Draft.pdf
>
>
> Take a look at the JSON built-in functions that are implemented in Postgres
> (http://www.postgresql.org/docs/9.3/static/functions-json.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 functions include ARRAY_TO_JSON, ROW_TO_JSON, TO_JSON, etc. The
> implementation of these built-in functions will be impacted by how JSON is
> stored in Phoenix. See PHOENIX-628. An initial implementation could work off
> of a simple text-based JSON representation and then when a native JSON type
> is implemented, they could be reworked to be more efficient.
