org.apache.hadoop.hbase.client.Table.batchCoprocessorService()

Creates an instance of the given {@link com.google.protobuf.Service} subclass for each tableregion spanning the range from the {@code startKey} row to {@code endKey} row (inclusive), allthe invocations to the same region server will be batched into one call. The coprocessor service is invoked according to the service instance, method name and parameters. @param methodDescriptor the descriptor for the protobuf service method to call. @param request the method call parameters @param startKey start region selection with region containing this row. If {@code null}, the selection will start with the first table region. @param endKey select regions up to and including the region containing this row. If {@code null}, selection will continue through the last table region. @param responsePrototype the proto type of the response of the method in Service. @param < R> the response type for the coprocessor Service method @throws ServiceException @throws Throwable @return a map of result values keyed by region name
