Hi folks, I’m using apache Cassandra 2.2.
Instance is configured with max_heap_size set at 16G, memtable_allocation_type is offheap_objects – total available memory is 62G on the server. There is nothing but Cassandra is running on my Linux server. My Cassandra instance is consuming all available memory on my machine! $ free -h total used free shared buffers cached Mem: 62G 62G 776M 184K 35M 42G -/+ buffers/cache: 19G 43G Swap: 4.0G 0B 4.0G Can you guys please suggest how I can limit memory usage of my Cassandra instance and why C* may be using all available memory? I’ll much appreciate your suggestions. Thanks/Asad
