Lars Hofhansl commented on PHOENIX-5559:
----------------------------------------
Thanks! Putting a breakpoint in
BaseScannerRegionObserver.throwIfScanOutOfRegion once with and once without the
patch will show the problem.
The only difference is that different start row for the scan, where with this
patch that start falls after any non-index key of for that region.
> With short index ids, index updates are written with the same index id in
> 4.15.0

> there are correctly two different index entries for both of the local indexes.
