Question

Cassandra will keep appending the records into the Commit Log and then to the Memtable.

a) True
b) False

Answer 1

Cassandra appends writes to the Commit Log and then to the Memtable, providing durability and availability in its write architecture.

Step-by-step explanation:

The statement is true. In Apache Cassandra, when a write operation occurs, Cassandra first appends the write to the Commit Log to ensure durability and then writes the data to an in-memory structure called the Memtable. Once the Memtable is full, the data is flushed to the SSTable on disk. This process is central to Cassandra's write architecture, providing a combination of high availability and data durability.
