    • executeQuery

      public void executeQuery(io.stargate.bridge.proto.QueryOuterClass.Query request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.QueryOuterClass.Response> responseObserver)
       Executes a single CQL query.

    • executeQueryWithSchema

      public void executeQueryWithSchema(io.stargate.bridge.proto.Schema.QueryWithSchema request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.Schema.QueryWithSchemaResponse> responseObserver)
       Executes a single CQL query, assuming that a keyspace with the given version hash exists on the
 bridge side.
 This is an optimization when the client builds a query based on a keyspace's contents: with
 this operation, it can use its local version of the keyspace (therefore avoiding an extra
 network hop to fetch it), and execute the query optimistically. If the keyspace has changed,
 the bridge will reply with the new version, allowing the client to retry.

    • executeBatch

      public void executeBatch(io.stargate.bridge.proto.QueryOuterClass.Batch request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.QueryOuterClass.Response> responseObserver)
       Executes a batch of CQL queries.

    • describeKeyspace

      public void describeKeyspace(io.stargate.bridge.proto.Schema.DescribeKeyspaceQuery request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.Schema.CqlKeyspaceDescribe> responseObserver)
       Similar to CQL "DESCRIBE KEYSPACE".
 Note that this operation does not perform any authorization check. The rationale is that, most
 of the time, client services use schema metadata to build another query that will be
 immediately executed with `ExecuteQuery` (which does check authorization).
 If that is not the case (e.g. you return the metadata directly to the client), you can check
 authorization explicitly with `AuthorizeSchemaReads`.

    • authorizeSchemaReads

      public void authorizeSchemaReads(io.stargate.bridge.proto.Schema.AuthorizeSchemaReadsRequest request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.Schema.AuthorizeSchemaReadsResponse> responseObserver)
       Checks whether the client is authorized to describe one or more schema elements.

    • getSupportedFeatures

      public void getSupportedFeatures(io.stargate.bridge.proto.Schema.SupportedFeaturesRequest request, io.grpc.stub.StreamObserver<io.stargate.bridge.proto.Schema.SupportedFeaturesResponse> responseObserver)
       Checks which features are supported by the persistence backend.
