Method Detail

getDdl

public graphql.GraphQL getDdl()

getSchemaFirstAdminGraphql

public graphql.GraphQL getSchemaFirstAdminGraphql()

getDmlAsync

public CompletionStage<Optional<graphql.GraphQL>> getDmlAsync(StargateBridgeClient bridge,
                                                              String keyspaceName)

Throws:

UnauthorizedKeyspaceException - (wrapped in the future) if the client is not authorized to read the keyspace's contents.

getDml

public Optional<graphql.GraphQL> getDml(StargateBridgeClient bridge,
                                        String keyspaceName)

putDml

public void putDml(io.stargate.bridge.proto.Schema.CqlKeyspaceDescribe keyspaceDescribe,
                   SchemaSource newSource,
                   graphql.GraphQL graphql)

Fill the cache entry when it's been computed externally. This is used after a schema-first deployment: we already have the GraphQL since it's been generated in order to validate the deployment, so use it instead of having the cache recompute it.

getDefaultKeyspaceNameAsync

public CompletionStage<Optional<String>> getDefaultKeyspaceNameAsync(StargateBridgeClient bridge)

getDefaultKeyspaceName

public Optional<String> getDefaultKeyspaceName(StargateBridgeClient bridge)
