There are 3 types of batch statements:
* Cassandra::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.
* Cassandra::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.
* Cassandra::BATCH_COUNTER - this batch is used for counter updates,
which are, unlike other writes, not idempotent.
/**
* Sends SQL statements to the database server returning the success state.
* Use this method only when the SQL statement sent to the server doesn't return any rows
* @param string $cqlStatement - CQL statement
* @param array $bindParams - bind parameters, default null
* @param array $bindTypes - bind types, default null
