Anoop Sam John commented on HBASE-11544:
----------------------------------------
Scan#setMaxResultSize(long) and/or conf "hbase.client.scanner.max.result.size"
should help in this right? We seems handling this in HRS with help of these 2
settings. By default there is no cap. So setting an appropriate value here
should help us to not OOM at HRS (?)
> [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.
