Functions

CassError

cass_batch_set_execute_as

( CassBatch * batch, const char * name )

Sets the name of the user to execute the batch as.

Parameters:
Name Type Details
in batch CassBatch *
in name const char *
Returns:
Type Details
CassError

CASS_OK if successful, otherwise an error occurred.
CassError

cass_batch_set_execute_as_n

( CassBatch * batch, const char * name, size_t name_length )

Same as CassBatch::cass_batch_set_execute_as, but with lengths for string parameters.

Parameters:
Name Type Details
in batch CassBatch *
in name const char *
in name_length size_t
Returns:
Type Details

cass_batch_new

( CassBatchType type )

Creates a new batch statement with batch type.

Requires Cassandra: 2.0+

Parameters:
Name Type Details
in type CassBatchType
Returns:
Type Details
CassBatch *

Returns a batch statement that must be freed.

void

cass_batch_free

( CassBatch * batch )

Frees a batch instance. Batches can be immediately freed after being executed.

Requires Cassandra: 2.0+

Parameters:
Name Type Details
in batch CassBatch *
CassError

cass_batch_set_keyspace

( CassBatch * batch, const char * keyspace )

Sets the batch’s keyspace. When using protocol v5 or greater it overrides the session’s keyspace for the batch.

Note: If not set explicitly then the batch will inherit the keyspace of the first child statement with a non-empty keyspace.

Parameters:
Name Type Details
in batch CassBatch *
in keyspace const char *
Returns:
Type Details
CassError

CASS_OK if successful, otherwise an error occurred.
CassError

cass_batch_set_keyspace_n

( CassBatch * batch, const char * keyspace, size_t keyspace_length )

Same as CassBatch::cass_batch_set_keyspace, but with lengths for string parameters.

Parameters:
Name Type Details
in batch CassBatch *
in keyspace const char *
in keyspace_length size_t
Returns:
Type Details
CassError

same as CassBatch::cass_batch_set_keyspace

cass_batch_set_consistency

( CassBatch * batch, CassConsistency consistency )

Sets the batch’s consistency level

Requires Cassandra: 2.0+

Parameters:
Name Type Details
in batch CassBatch *
in consistency CassConsistency

The batch’s write consistency.
Returns:
Type Details
CassError

CASS_OK if successful, otherwise an error occurred.
CassError

cass_batch_set_serial_consistency

( CassBatch * batch, CassConsistency serial_consistency )

Sets the batch’s serial consistency level.

Requires Cassandra: 2.0+

Default: Not set

Parameters:
Name Type Details
in batch CassBatch *

CASS_OK if successful, otherwise an error occurred.
CassError

cass_batch_set_request_timeout

( CassBatch * batch, cass_uint64_t timeout_ms )

Sets the batch’s timeout for waiting for a response from a node.

Default: Disabled (use the cluster-level request timeout)

Parameters:
Name Type Details
in batch CassBatch *
in timeout_ms cass_uint64_t

Request timeout in milliseconds. Use 0 for no timeout or CASS_UINT64_MAX to disable (to use the cluster-level request timeout).
Returns:
Type Details

CassError

cass_batch_set_is_idempotent

( CassBatch * batch, cass_bool_t is_idempotent )

Returns:
Type Details
CassError

CASS_OK if successful, otherwise an error occurred.
