---------------------------------
Attachment: 6711-0.96-v1.txt
Here's a simple patch for that.
The performance implications will typically be negligible here (except for
extreme cases), but it reads better.
> Avoid local results copy in StoreScanner

> In StoreScanner the number of results is limited to avoid OOMs.
> However, this is done by first adding the KV into a local ArrayList and then
> copying the entries in this list to the final result list.
> In turns out the this temporary list is only used to keep track of the size
> of the result set in this loop. Can use a simple int instead.
