Add support to batch insert or update data to Cassandra using the
cass_batch_*api in the DataStax driver.I would like to get some feedback on whether we should expose the batch API like this where the client needs to explicitly control the size of the batch or if we should have some mechanism to let the client add statements to the batch and swift-cassandra-driver automatically flushes a batch when some threshold is reached. The tricky part here would be defining that threshold. As far as I could tell there are limits to the maximum batch size in Cassandra but I haven’t found a good way to (a) figure out that limit for the Cassandra instance that we are connected to and (b) counting the number of bytes that are currently included in a batch to compare it against that maximum batch size limit.
