Apache Cassandra offers three compaction strategies, each suited to different workloads. STCS is ideal for write-heavy workloads, LCS excels in read-intensive environments, and TWCS is tailored for time-series data.
Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL. For more information, see the Apache Cassandra web site.
