Review Comment:
As we have to handle different cases like, multitenant tables, salted
tables, we decided to take care of it in later iterations.
> Extend UncoveredGlobalIndexRegionScanner for CDC region scanner usecase
> -----------------------------------------------------------------------
>
> Key: PHOENIX-7015
> URL: https://issues.apache.org/jira/browse/PHOENIX-7015
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Viraj Jasani
> Priority: Major
>
> For CDC region scanner usecase, extend UncoveredGlobalIndexRegionScanner to
> CDCUncoveredGlobalIndexRegionScanner. The new region scanner for CDC performs
> raw scan to index table and retrieve data table rows from index rows.
> Using the time range, it can form a JSON blob to represent changes to the row
> including pre and/or post row images.
