Constants
CONSISTENCY_ANY
= 0
Consistency level ANY means the request is fulfilled as soon as the data has been written on the Coordinator. Requests with this consistency level are not guranteed to make it to Replica nodes.
CONSISTENCY_ONE
= 1
Consistency level ONE gurantess that data has been written to at least one Replica node.
CONSISTENCY_LOCAL_ONE
= 10
Same as CONSISTENCY_ONE, but confined to the local data center. This consistency level works only with NetworkTopologyStrategy replication.
CONSISTENCY_TWO
= 2
Consistency level TWO gurantess that data has been written to at least two Replica nodes.
CONSISTENCY_THREE
= 3
Consistency level THREE gurantess that data has been written to at least three Replica nodes.
CONSISTENCY_QUORUM
= 4
Consistency level QUORUM gurantess that data has been written to at least the majority of Replica nodes. How many nodes exactly are a majority depends on the replication factor of a given keyspace and is calculated using the formula ceil(RF / 2 + 1), where ceil is a mathematical ceiling function and RF is the replication factor used. For example, for a replication factor of 5, the majority is ceil(5 / 2 + 1) = 3.
CONSISTENCY_LOCAL_QUORUM
= 6
Same as CONSISTENCY_QUORUM, but confined to the local data center. This consistency level works only with NetworkTopologyStrategy replication.
CONSISTENCY_EACH_QUORUM
= 7
Consistency level EACH_QUORUM gurantess that data has been written to at least a majority Replica nodes in all datacenters. This consistency level works only with NetworkTopologyStrategy replication.
CONSISTENCY_ALL
= 5
Consistency level ALL gurantess that data has been written to all Replica nodes.
CONSISTENCY_SERIAL
= 8
This is a serial consistency level, it is used in conditional updates, e.g. (CREATE|INSERT ... IF NOT EXISTS), and should be specified as the serial_consistency option of the Cassandra\ExecutionOptions instance.
Consistency level SERIAL, when set, ensures that a Paxos commit fails if any of the replicas is down.
CONSISTENCY_LOCAL_SERIAL
= 9
Same as CONSISTENCY_SERIAL, but confined to the local data center. This consistency level works only with NetworkTopologyStrategy replication.
VERIFY_NONE
= 0
Perform no verification of Cassandra nodes when using SSL encryption.
VERIFY_PEER_CERT
= 1
Verify presence and validity of SSL certificates of Cassandra.
VERIFY_PEER_IDENTITY
= 2
Verify that the IP address matches the SSL certificate’s common name or one of its subject alternative names. This implies the certificate is also present.
BATCH_LOGGED
= 0
BATCH_UNLOGGED
= 1
BATCH_COUNTER
= 2
TYPE_TEXT
= ‘text’
When using a map, collection or set of type text, all of its elements must be strings.
TYPE_ASCII
= ‘ascii’
When using a map, collection or set of type ascii, all of its elements must be strings.
TYPE_VARCHAR
= ‘varchar’
When using a map, collection or set of type varchar, all of its elements must be strings.
TYPE_BIGINT
= ‘bigint’
When using a map, collection or set of type bigint, all of its elements must be instances of Cassandra\Bigint.
TYPE_BLOB
= ‘blob’
When using a map, collection or set of type blob, all of its elements must be instances of Cassandra\Blob.
TYPE_BOOLEAN
= ‘boolean’
When using a map, collection or set of type boolean, all of its elements must be booleans.
TYPE_COUNTER
= ‘counter’
When using a map, collection or set of type counter, all of its elements must be instances of Cassandra\Bigint.
TYPE_DECIMAL
= ‘decimal’
When using a map, collection or set of type decimal, all of its elements must be instances of Cassandra\Decimal.
TYPE_DOUBLE
= ‘double’
When using a map, collection or set of type double, all of its elements must be doubles.
TYPE_FLOAT
= ‘float’
When using a map, collection or set of type float, all of its elements must be instances of Cassandra\Float.
TYPE_INT
= ‘int’
When using a map, collection or set of type int, all of its elements must be ints.
TYPE_TIMESTAMP
= ‘timestamp’
When using a map, collection or set of type timestamp, all of its elements must be instances of Cassandra\Timestamp.
TYPE_UUID
= ‘uuid’
When using a map, collection or set of type uuid, all of its elements must be instances of Cassandra\Uuid.
TYPE_VARINT
= ‘varint’
When using a map, collection or set of type varint, all of its elements must be instances of Cassandra\Varint.
TYPE_TIMEUUID
= ‘timeuuid’
When using a map, collection or set of type timeuuid, all of its elements must be instances of Cassandra\Timeuuid.
TYPE_INET
= ‘inet’
When using a map, collection or set of type inet, all of its elements must be instances of Cassandra\Inet.
VERSION
= ‘1.0.0-beta’
Current version of the extension.
