> Currently the only way to insert multiple records on the same partition key,
> atomically and using PreparedStatements is to use a CQL BATCH command.
> Unfortunately when doing so the amount of records to be inserted must be
> known prior to prepare the statement which is rarely the case. Thus the only
> workaround if one want to keep atomicity is currently to use unprepared
> statements which send a bulk of CQL strings and is fairly inefficient.
> Therefore CQL Protocol should allow clients to send multiple
> PreparedStatements to be executed with similar guarantees and semantic as CQL
> BATCH command.
