>          Issue Type: Improvement
>          Components: sql
>    Affects Versions: 2.4
>            Reporter: Valentin Kulichenko

>             Fix For: 2.5
> Currently, if SQL on heap cache is enabled, there is no clear way to control 
> the size of this cache. Looks like its evictions basically depend on 
> evictions in off-heap, so it's really to get OOME. Not very usable.
> The easiest improvement would be to have a knob (configuration parameter or 
> system property) that would control the size of underlying concurrent map 
> that stores cached rows.
