ProtocolVersion Enumeration
Specifies the different protocol versions and provides methods (via extension methods) to check whether a feature is supported in an specific version

Namespace: Cassandra
Assembly: Cassandra (in Cassandra.dll) Version: 3.4.0
Syntax

Copy
public enum ProtocolVersion
Members
  Member nameValueDescription
V11 Cassandra protocol v1, supported in Apache Cassandra 1.2-->2.2.
V22 Cassandra protocol v2, supported in Apache Cassandra 2.0-->2.2.
V33 Cassandra protocol v3, supported in Apache Cassandra 2.1-->3.x.
V44 Cassandra protocol v4, supported in Apache Cassandra 2.2-->3.x.
V55 Cassandra protocol v5, in beta from Apache Cassandra 3.x+. Currently not supported by the driver.
MaxSupported4 The higher protocol version that is supported by this driver.

When acquiring the first connection, it will use this version to start protocol negotiation.

MinSupported1 The lower protocol version that is supported by this driver.
