             Summary: Eviction policy for SQL on-heap row cache
                 Key: IGNITE-7470
                 URL: https://issues.apache.org/jira/browse/IGNITE-7470
             Project: Ignite
          Issue Type: New Feature
          Components: sql
    Affects Versions: 2.4
            Reporter: Denis Magda

SQL on-heap row cache was introduced in Ignite 2.4:


The cache can occupy as much RAM as allocated and used for off-heap data regions. If a user
stores dozens or hundreds of gigabytes in the data regions the on-heap row cache will become
enormous and the cluster will suffer from atrocious GC pauses.

Let's come up with an eviction policy for this cache.
