-------------------------------------------
Summary: CQL Protocol should allow multiple PreparedStatements to
be atomically executed
Key: CASSANDRA-4693
URL: https://issues.apache.org/jira/browse/CASSANDRA-4693
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Michaël Figuière
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.
