Syntax

public class Metadata : IDisposable

The Metadata type exposes the following members.

Properties

	Name	Description
	ClusterName	Returns the name of currently connected cluster.

Methods

	Name	Description
	AllHosts	Returns all known hosts of this cluster.
	AllReplicas
	CheckSchemaAgreementAsync	Initiates a schema agreement check. Schema changes need to be propagated to all nodes in the cluster. Once they have settled on a common version, we say that they are in agreement. This method does not perform retries so MaxSchemaAgreementWaitSeconds does not apply.
	Dispose	Releases all resources used by the Metadata
	GetAggregate	Gets the definition associated with a aggregate from Cassandra
	GetFunction	Gets the definition associated with a User Defined Function from Cassandra
	GetHost
	GetKeyspace	Returns metadata of specified keyspace.
	GetKeyspaces	Returns a collection of all defined keyspaces names.
	GetMaterializedView	Returns the view metadata for the provided view name in the keyspace.
	GetReplicas(Byte)
	GetReplicas(String, Byte)	Get the replicas for a given partition key and keyspace
	GetTable	Returns TableMetadata for specified table in specified keyspace.
	GetTables	Returns names of all tables which are defined within specified keyspace.
	GetUdtDefinition	Gets the definition associated with a User Defined Type from Cassandra
	GetUdtDefinitionAsync	Gets the definition associated with a User Defined Type from Cassandra
	RefreshSchema	Updates the keyspace and token information
	RefreshSchemaAsync	Updates the keyspace and token information
	ShutDown
