             Summary: Need to have better control on the size of SQL on heap 
cache
                 Key: IGNITE-8139
                 URL: https://issues.apache.org/jira/browse/IGNITE-8139
             Project: Ignite
          Issue Type: Improvement
          Components: sql
    Affects Versions: 2.4
            Reporter: Valentin Kulichenko
            Assignee: Vladimir Ozerov
             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.
