How does Cassandra write?

Question Posted / arti singh


How does Cassandra write?..

Answer / Taran Jeet Singh Budhiraja

When a write request is received in Cassandra, the update is initially stored in the memtable. The data remains in the memtable until it reaches a predefined size or age (time since last update), at which point it gets merged with other SSTables during compaction to reduce the number of files and improve performance.
