Enum Class ProtocolVersion

java.lang.Object
java.lang.Enum<ProtocolVersion>
org.apache.cassandra.transport.ProtocolVersion
All Implemented Interfaces:
Serializable, Comparable<ProtocolVersion>, Constable
public enum ProtocolVersion extends Enum<ProtocolVersion> implements Comparable<ProtocolVersion>
The native (CQL binary) protocol version. Some versions may be in beta, which means that the client must specify the beta flag in the envelope's header for the version to be considered valid. Beta versions must have the word "beta" in their description, this is mandated by the specs.

      public static final EnumSet<ProtocolVersion> SUPPORTED
      All supported versions, published as an enumset

    • UNSUPPORTED

      public static final EnumSet<ProtocolVersion> UNSUPPORTED
      Old unsupported versions, this is OK as long as we never add newer unsupported versions

    • CURRENT

      public static final ProtocolVersion CURRENT
      The preferred version. When updating this remember to also update the MULTI_UPGRADES in cassandra-dtest/upgrade_tests/upgrade_through_versions_test.py
