Batch packet (Cassandra)

This packet is sent by the client to execute one or more queries at once.

Properties

• batchType (int): 0 == logged, 1 == unlogged, 2 == counter

• queries (list<BatchQuery>): the queries to execute -- see below for details on the BatchQuery object

• consistency (int): the consistency level for the operation. See Cassandra common flags for details.

• serialConsistency (int): the consistency level for the serial phase of conditional updates. See Cassandra common flags for details. This can only be SERIAL or LOCAL_SERIAL. If not present, defaults to SERIAL. This option is ignored for anything other than a conditional update/insert.

• flagWithSerialConsistency (boolean): if true, serialConsistency is specified.

• flagWithDefaultTimestamp (boolean); if true, then defaultTimestamp is specified.

• flagWithNamesForValues (boolean): currently unused

• flagWithKeyspace (boolean): if true, then keyspaceName is specified

• flagWithNowInSeconds (boolean): if true, then nowInSeconds is valid

• defaultTimestamp (long): set if flagWithDefaultTimestamp is set. The default timestamp for the query in microseconds.

• keyspaceName (string): the keyspace in which the queries should be executed.

• nowInSeconds (int): the current time (now) for the query
