Hi there, we just finished upgrading sstables on a single node after upgrading from 2.2.14 to 3.11.4. Since then, we noted a drastic increase of off heap memory consumption. This is due to increased bloom filter size.
According to cfstats output "Bloom filter off heap memory used" increased by a factor between 7 and 8. That means that while bloom filters took 1 GB of off heap storage with 2.2.14, they fill around 7.5 GB with 3.11.4. Did anyone observe something similar? Have there been bigger changes to the bloom filter implementation between those versions?
