Hi Igor, I noticed that current Cassandra store implementation doesn't support batching for writeAll and deleteAll methods, it simply executes all updates one by one (asynchronously in parallel).
I think it can be useful to provide such support and created a ticket [1]. Can you please give your input on this? Does it make sense in your opinion? [1] https://issues.apache.org/jira/browse/IGNITE-3588 -Val
