How to multi insert rows in cassandra

Question

What is the most efficient way of inserting multiple rows in cassandra column family. Is it possible to do this in a single call.

Right now my approach is to addinsert m

Answer 1

When trying to insert multiple rows. Database connection RTT could be the performance bottle neck. In that case, we generally need a way to avoid waiting for one INSERT to finish so that we can begin our next INSERT.Currently there are two ways as far as I know:

• If data consistency matters, use LOGGED BATCH, but as this question said, BATCH may not have a performance boost in all the situation.
• Otherwise, use a async api in the Cassandra client library, for example in python there is a execute_async method

Also, you can prepare the SQL statement before execute it. I haven't test the overall performance of a prepared statement vs plain insert. But I think if there are thousands INSERT or more you should get a performance boost.
