Method Detail

hosts

public HectorCassandraClientConfigurer hosts(String hosts)

Cassandra hosts

Parameters:

hosts - Command delimited list of Cassandra hosts (hostnames or ipaddresses)

Returns:

this instance.

port

public HectorCassandraClientConfigurer port(Integer port)

Sets the port matching the host name of the Cassandra cluster to connect to.

Parameters:

port - The cassandra port. Set null to use the default port number CassandraHost.DEFAULT_PORT

Returns:

this instance.

keyspaceName

clusterName - The cluster 'tag' name.

Returns:

this instance.

columnFamilyGcGraceSeconds

public HectorCassandraClientConfigurer columnFamilyGcGraceSeconds(Integer columnFamilyGcGraceSeconds)

writeConsistencyLevel - The consistencly level used for write/update/remove operations. (default: CassandraConsistencyLevel.QUORUM)

Returns:

HectorCassandraClientConfigurer

create

public HectorCassandraClient create()

Returns:

An instance of HectorCassandraClient matching this configurer configuration.
