BATCH (CQL)

Groups multiple CQL statements into one request. Useful for writing to denormalized tables atomically. UNLOGGED is faster for multi-partition writes but not atomic across partitions.

Syntax

cassandra

BEGIN [UNLOGGED] BATCH
  statement;
APPLY BATCH;

Example

cassandra

BEGIN BATCH
  INSERT INTO following (follower_id, followed_id) VALUES (?, ?);
  INSERT INTO followers (followed_id, follower_id) VALUES (?, ?);
APPLY BATCH;
