Hi,
it seems you are doing some thing wrong in your model, why can you go with

It seems like the only solution which won't have race conditions is to use

Hi,
You can't. Batches are only available for INSERT, UPDATE and DELETE
operations. Batches exist to give Cassandra some atomicity, as in, or all
operations succeed or all fail.

As an alternative, you could always execute the async to Cassandra and then
iterate over the results as they come in.
