Answer / Ashvani Kumar Singh
"Cassandra performs write operations by first writing the operation to the CommitLog. Then, it writes the data to the Memtable if there is space available or flushes an existing Memtable if it's full. Once a certain threshold is reached, Memtables are compacted into SSTables, which become the final persistent representation of the data."
