Interface BeamFnDataBufferingOutboundObserver<T>

All Superinterfaces:

java.lang.AutoCloseable, CloseableFnDataReceiver<T>, FnDataReceiver<T>

All Known Implementing Classes:

BeamFnDataSizeBasedBufferingOutboundObserver, BeamFnDataTimeBasedBufferingOutboundObserver

public interface BeamFnDataBufferingOutboundObserver<T>
extends CloseableFnDataReceiver<T>

A buffering outbound FnDataReceiver for the Beam Fn Data API.

Encodes individually consumed elements with the provided Coder producing a single BeamFnApi.Elements message when the buffer threshold is surpassed.

The default size-based buffer threshold can be overridden by specifying the experiment data_buffer_size_limit=<bytes>

The default time-based buffer threshold can be overridden by specifying the experiment data_buffer_time_limit_ms=<milliseconds>
