Explain the term memtable?

Question Posted / punkhuri singh


Explain the term memtable?..

Answer / Lucky Kaushik

A Memtable is an in-memory data structure in Cassandra that stores rows of data. Each Memtable contains key-value pairs and a compacted form of previous Memtables, allowing for efficient read and write operations. When a write operation occurs, it gets written to the Memtable. Once the size limit is reached or during compaction, the Memtable is flushed to SSTable files for persistence.
