Hello Ilya, I have found that cause of problem the objects which have different size of data. As result I have situation where pageFillFactor increased and offHeapSize is decreased and this trend never end.
Grafana screen: https://www.awesomescreenshot.com/image/3619800/ad604d44bae0f241a2618197c2be8af4 I updated reproducer with static data set in csv ( ignite-server-docker/src/main/docker/5.csv ) . Reproducer : https://github.com/SergeyMagid/ignite-reproduce-grow-memory Can you look at this ? Can this be a bug or we should use different data model? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
