Hi,
I'm seeing some strange behavior of the memtables, both in 1.2.13 and 2.0.7, basically it looks like it's using 10x less memory than it should based on the documentation and options. 10GB heap for both clusters. 1.2.x should use 1/3 of the heap for memtables, but it uses max ~300mb before flushing 2.0.7, same but 1/4 and ~250mb In the 2.0.7 cluster I set the memtable_total_space_in_mb to 4096, which then allowed cassandra to use up to ~400mb for memtables... I'm now running with 20480 for memtable_total_space_in_mb and cassandra is using ~2GB for memtables. Soo, off by 10 somewhere? Has anyone else seen this? Can't find a JIRA for any bug connected to this. java 1.7.0_55, JNA 4.1.0 (for the 2.0 cluster) BR Johan
