    • Method Detail

      • readRows

        default void readRows​(ReadRowsRequest request,
                      io.grpc.stub.StreamObserver<ReadRowsResponse> responseObserver)
         Streams back the contents of all requested rows in key order, optionally
 applying the same Reader filter to each. Depending on their size,
 rows and cells may be broken up across multiple responses, but
 atomicity of each row will still be preserved. See the
 ReadRowsResponse documentation for details.

      • sampleRowKeys

        default void sampleRowKeys​(SampleRowKeysRequest request,
                           io.grpc.stub.StreamObserver<SampleRowKeysResponse> responseObserver)
         Returns a sample of row keys in the table. The returned row keys will
 delimit contiguous sections of the table of approximately equal size,
 which can be used to break up the data for distributed tasks like
 mapreduces.

      • mutateRow

        default void mutateRow​(MutateRowRequest request,
                       io.grpc.stub.StreamObserver<MutateRowResponse> responseObserver)
         Mutates a row atomically. Cells already present in the row are left
 unchanged unless explicitly changed by `mutation`.

      • mutateRows

        default void mutateRows​(MutateRowsRequest request,
                        io.grpc.stub.StreamObserver<MutateRowsResponse> responseObserver)
         Mutates multiple rows in a batch. Each individual row is mutated
 atomically as in MutateRow, but the entire batch is not executed
 atomically.

      • pingAndWarm

        default void pingAndWarm​(PingAndWarmRequest request,
                         io.grpc.stub.StreamObserver<PingAndWarmResponse> responseObserver)
         Warm up associated instance metadata for this connection.
 This call is not required but may be useful for connection keep-alive.

      • readModifyWriteRow

        default void readModifyWriteRow​(ReadModifyWriteRowRequest request,
                                io.grpc.stub.StreamObserver<ReadModifyWriteRowResponse> responseObserver)
         Modifies a row atomically on the server. The method reads the latest
 existing timestamp and value from the specified columns and writes a new
 entry based on pre-defined read/modify/write rules. The new value for the
 timestamp is the greater of the existing timestamp or the current server
 time. The method returns the new contents of all modified cells.

      • generateInitialChangeStreamPartitions

        default void generateInitialChangeStreamPartitions​(GenerateInitialChangeStreamPartitionsRequest request,
                                                   io.grpc.stub.StreamObserver<GenerateInitialChangeStreamPartitionsResponse> responseObserver)
         NOTE: This API is intended to be used by Apache Beam BigtableIO.
 Returns the current list of partitions that make up the table's
 change stream. The union of partitions will cover the entire keyspace.
 Partitions can be read with `ReadChangeStream`.

      • readChangeStream

        default void readChangeStream​(ReadChangeStreamRequest request,
                              io.grpc.stub.StreamObserver<ReadChangeStreamResponse> responseObserver)
         NOTE: This API is intended to be used by Apache Beam BigtableIO.
 Reads changes from a table's change stream. Changes will
 reflect both user-initiated mutations and mutations that are caused by
 garbage collection.
