> Setting scanner caching is somewhat of a black art. It's hard to estimate
> ahead of time how large the result set will be.
> I propose we hbase.client.scanner.max.result.size to 2mb. That is good
> compromise between performance and buffer usage on typical networks (avoiding
> OOMs when the caching was chosen too high).
> To an HTable client this is completely transparent.
