Hi everybody. I stumbled this morning upon this excellent blog post [1] from the cloudera guys in which they explain how they changed the way the memstore allocates memory to reduce fragmentation, and thus stop-the-world garbage collections. Speaking from ignorance, memstore sounds like memtables in cassandra. Could this technique be applied in cassandra too?
