Dear Community, In Cassandra 3.11.2, there are 3 choices for the type of Memtable allocation and as per my understanding, if I want to keep Memtables on JVM heap I can use heap_buffers and if I want to store Memtables outside of JVM heap then I've got 2 options offheap_buffers and offheap_objects.
What exactly is the difference between the 2 choices given for off-heap allocation? Also, the permitted memory space to be used for Memtables can be set at 2 places in the YAML file, i.e. memtable_heap_space_in_mb and memtable_offheap_space_in_mb. Do I need to configure some space in both heap and offheap, irrespective of the Memtable allocation type or do I need to set only one of them based on my Memtable allocation type i.e. memtable_heap_space_in_mb when using heap buffers and memtable_offheap_space_in_mb only when using either of the other 2 offheap options? https://stackoverflow.com/questions/49874917/memtable-type-and-size-allocation Thanks and regards, Vishal Sharma "Confidentiality Warning: This message and any attachments are intended only for the use of the intended recipient(s). are confidential and may be privileged.
