"Write performance in Cassandra is excellent. The internals are specifically geared towards a heavy-write system. It writes to a memory table and a serial commit log, and every so often the memory table is flushed to disk in what the Big Table paper describes as a sorted strings table, often called an SSTable — an immutable data structure.
