Description

Moving my proposed patch for ~~CASSANDRA-15367~~ here. Contended memtable updates currently waste memtable memory each time they fail to apply. This patch avoids this problem by ensuring we only copy data once onto the memtable, and reconcile this new data for all future attempts to insert.
