Enis Soztutar commented on HBASE-11544:
---------------------------------------
There is one more issue here. We are changing the RegionScanner interface which
is marked Stable for coprocessors which we also say that we will not break (see
the book). Phoenix have a lot of {{RegionScanner}}'s which does not compile
anymore.
Can we do an internal-shim here?
> [Ergonomics] hbase.client.scanner.caching is dogged and will try to return
> batch even if it means OOME

> Running some tests, I set hbase.client.scanner.caching=1000. Dataset has
> large cells. I kept OOME'ing.
> Serverside, we should measure how much we've accumulated and return to the
> client whatever we've gathered once we pass out a certain size threshold
> rather than keep accumulating till we OOME.
