Method Summary

Modifier and Type	Method and Description
CreateDseKeyspaceStart	ifNotExists() Adds IF NOT EXISTS to the create keyspace specification.
default CreateDseKeyspace	withNetworkTopologyStrategy(Map<String,Integer> replications) Adds NetworkTopologyStrategy replication options with the given data center replication factors.
CreateDseKeyspace	withReplicationOptions(Map<String,Object> replicationOptions) Adds 'replication' options.
default CreateDseKeyspace	withSimpleStrategy(int replicationFactor) Adds SimpleStrategy replication options with the given replication factor.

Method Detail

ifNotExists

@NonNull
CreateDseKeyspaceStart ifNotExists()

Adds IF NOT EXISTS to the create keyspace specification. This indicates that the keyspace should not be created it already exists.

withReplicationOptions

@NonNull
CreateDseKeyspace withReplicationOptions(@NonNull
                                                  Map<String,Object> replicationOptions)

Adds 'replication' options. One should only use this when they have a custom replication strategy, otherwise it is advisable to use withSimpleStrategy(int) or withNetworkTopologyStrategy(Map).

Specified by:

withReplicationOptions in interface KeyspaceReplicationOptions<CreateDseKeyspace>

withSimpleStrategy

@NonNull
default CreateDseKeyspace withSimpleStrategy(int replicationFactor)

Adds SimpleStrategy replication options with the given replication factor.

Note that using this will overwrite any previous use of this method or withNetworkTopologyStrategy(Map).

Specified by:

withSimpleStrategy in interface KeyspaceReplicationOptions<CreateDseKeyspace>

withNetworkTopologyStrategy

@NonNull
default CreateDseKeyspace withNetworkTopologyStrategy(@NonNull
                                                               Map<String,Integer> replications)

Adds NetworkTopologyStrategy replication options with the given data center replication factors.

Note that using this will overwrite any previous use of this method or withSimpleStrategy(int).

Specified by:

withNetworkTopologyStrategy in interface KeyspaceReplicationOptions<CreateDseKeyspace>

Parameters:

replications - Mapping of data center name to replication factor to use for that data center.
