> 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
> Priority: Major
> Labels: sql-stability
>
> SQL on-heap row cache was introduced in Ignite 2.4:
> [https://apacheignite-sql.readme.io/v2.3/docs/performance-and-debugging_24_hidden#sql-on-heap-row-cache]
> 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.
