Alexey Kukushkin updated IGNITE-16431: -------------------------------------- Remaining Estimate: 40h (was: 168h) Original Estimate: 40h (was: 168h) > Entry expiration requires twice the entry size of heap > ------------------------------------------------------ > > Key: IGNITE-16431 > URL: https://issues.apache.org/jira/browse/IGNITE-16431 > Project: Ignite > Issue Type: Improvement > Affects Versions: 2.12 > Reporter: Alexey Kukushkin > Priority: Major > Labels: cggg > Attachments: 500MB-put-expiry-master.png > > Original Estimate: 40h > Remaining Estimate: 40h > > Ignite takes twice the entry size off the heap to expire the entry when > {{{}eagerTtl=true{}}}. See the attached heap memory usage diagram of putting > and then expiring a 500MB entry in Ignite. > This makes Ignite inefficient with handling large objects causing > {{OutOfMemory}} errors. > Do we really need loading entry's value on heap at all to expiry the entry? > Please enhance Ignite cache entry expiration not to load the entry's value on > heap even once or explain why it is not possible. > !500MB-put-expiry-master.png! -- This message was sent by Atlassian Jira (v8.20.7#820007)
