Cassandra is optimized for writing large amounts of data very quickly. Cassandra writes all incoming data in an append-only manner in internal files called SSTables. These SSTables hence contain newly inserted data and updates/deletes of previously inserted data. What is Compaction? Cassandra Compaction is a process of reconciling various copies of data spread across distinct...
