Denis Magda created IGNITE-7470: ----------------------------------- 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: [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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
