tricolor2 opened a new pull request #440: PHOENIX-4311: Unnest Support URL: https://github.com/apache/phoenix/pull/440 I have started the implementation of the UNNEST function support. I've implemented similarly to Postgresql. So far I can perform a select, aggregations, use limit, upsert using it. My next step is to implement the Where compiler to create a post-filter for the UNNESTED column but I need your feed back on what is implemented so far before doing so. Missing components are: - WHERE compiler - JOIN support Improvements: - Add to the explain plan the UNNEST columns - Add the post-unnest filter information to the plan when the where will be implemented - Return a ProjectedColumnExpression column instead of KeyValueColumnExpression to save bandwidth Best regards,
