> PHOENIX-7460 takes care of updating Phoenix CDC Stream metadata when a data
> table region splits. Similarly, when more than one regions are merged into
> single region, we should update the stream metadata to reflect the
> parent/child relationship among the stream partitions that virtually
> represent data table regions.
> HBase MasterObserver coproc hook to be used after successful region merge:
> {code:java}
> /**
> * called after the regions merge.
> * @param ctx the environment to interact with the framework and master
> */
> default void postCompletedMergeRegionsAction(
> final ObserverContext<MasterCoprocessorEnvironment> ctx, final RegionInfo[]
> regionsToMerge,
> final RegionInfo mergedRegion) throws IOException {
> }
> {code}
