class BatchStatement

Batch statements are used to execute a series of simple or prepared statements.

There are 3 types of batch statements:

• Dse::BATCH_LOGGED - this is the default batch type. This batch guarantees that either all or none of its statements will be executed. This behavior is achieved by writing a batch log on the coordinator, which slows down the execution somewhat.
• Dse::BATCH_UNLOGGED - this batch will not be verified when executed, which makes it faster than a LOGGED batch, but means that some of its statements might fail, while others - succeed.
• Dse::BATCH_COUNTER - this batch is used for counter updates, which are, unlike other writes, not idempotent.
