Subject [jira] [Commented] (CASSANDRA-4693) CQL Protocol should allow multiple PreparedStatements to be atomically executed

Aleksey Yeschenko commented on CASSANDRA-4693:
----------------------------------------------

Can't get it to build - two execute() methods in BatchStatement with the same erasure :(

> 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.
