Insert multiple records at once in Cassandra

Question

I've been researching a lot about how to insert multiple records in direct cassandra cqlsh console. I found something about batch, so I thought of using it with a loop (for, while) but it seems that Cassandra does not support batch.

How could insert multiple records in direct cassandra console? There is something like stored procedure in cassandra?

Answer 1

Cassandra does not (at this time) have stored procedures, but you should be able to accomplish this with a batch statement . Essentially you should be able to encapsulate multiple INSERT s inside of BEGIN BATCH and APPLY BATCH statements. This example is from the DataStax documentation on batch operations.

BEGIN BATCH
  INSERT INTO purchases (user, balance) VALUES ('user1', -8) USING TIMESTAMP 19998889022757000;
  INSERT INTO purchases (user, expense_id, amount, description, paid)
    VALUES ('user1', 1, 8, 'burrito', false);
APPLY BATCH;

Check the doc linked above for more information.

Edit:

If you are meaning to INSERT several million records at once, then you should consider other methods. The cqlsh COPY command is a viable alternative (for a few million records or less) or the Cassandra Bulk Loader for 10 million or more.
