    Description
    io.smallrye.mutiny.Uni<io.stargate.bridge.proto.Schema.AuthorizeSchemaReadsResponse>
    authorizeSchemaReads(io.stargate.bridge.proto.Schema.AuthorizeSchemaReadsRequest request)
    Checks whether the client is authorized to describe one or more schema elements.
    io.smallrye.mutiny.Uni<io.stargate.bridge.proto.Schema.CqlKeyspaceDescribe>
    describeKeyspace(io.stargate.bridge.proto.Schema.DescribeKeyspaceQuery request)
    Similar to CQL "DESCRIBE KEYSPACE".
    io.smallrye.mutiny.Uni<io.stargate.bridge.proto.QueryOuterClass.Response>
    executeBatch(io.stargate.bridge.proto.QueryOuterClass.Batch request)
    Executes a batch of CQL queries.

    • executeQuery

      public io.smallrye.mutiny.Uni<io.stargate.bridge.proto.QueryOuterClass.Response> executeQuery(io.stargate.bridge.proto.QueryOuterClass.Query request)
      Description copied from interface: StargateBridge
        Executes a single CQL query.
      Specified by:
      executeQuery in interface StargateBridge

    • executeQueryWithSchema

      public io.smallrye.mutiny.Uni<io.stargate.bridge.proto.Schema.QueryWithSchemaResponse> executeQueryWithSchema(io.stargate.bridge.proto.Schema.QueryWithSchema request)
      Description copied from interface: StargateBridge
        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.

      executeQueryWithSchema in interface StargateBridge

    • executeBatch

      public io.smallrye.mutiny.Uni<io.stargate.bridge.proto.QueryOuterClass.Response> executeBatch(io.stargate.bridge.proto.QueryOuterClass.Batch request)
      Description copied from interface: StargateBridge
        Executes a batch of CQL queries.
      Specified by:
      executeBatch in interface StargateBridge

    • describeKeyspace

      public io.smallrye.mutiny.Uni<io.stargate.bridge.proto.Schema.CqlKeyspaceDescribe> describeKeyspace(io.stargate.bridge.proto.Schema.DescribeKeyspaceQuery request)
      Description copied from interface: StargateBridge
        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`.
