Hi, We have Cassandra 2.2.1 on Windows 2008R2-64-bit. We are noticing that during compaction Cassandra consumes all the available memory for the VM and bring the VM to a crawl. compaction settings are default, and we are using sized tiered compaction.
When investigating this, we find through VMMAP that the memory is consumed by mapped files. These are almost all the sstables (index and data) for all keyspaces, mapped into memory (system and user defined keyspaces) . Is this normal, or should these files not be mapped into memroy after compaction? Regards, Alaa -- *This message may contain confidential and privileged information.
