Jin Xing updated FLINK-20716:
-----------------------------
Description: In current "pluggable shuffle service", IndexedInputGate
defines the reading for a single intermediate result (doc of InputGate) and
InputChannel defines a single reading channel in IndexedInputGate.
IndexedInputGate consists of a number of InputChanels. Current fields of
InputChannel are mainly some descriptions or metrics for a single channel. But
we found SingleInputGate is mixed in. From our understanding, SingleInputGate
is a specific implementation in "Netty shuffle service" and should not be
exposed by "pluggable shuffle service". (was: IndexedInputGate provided by
pluggable shuffle service as a public interface, and intend to allow user to
extend/customize the shuffle-read behavior. Currently its method of
IndexedInputGate#getChannel returns InputChannel, which from my understanding
binds to Netty shuffle service implementation. Should we keep IndexedInputGate
independent ?)
> Pluggable shuffle service public interface IndexedInputGate mixed with Netty
> shuffle service implementation.
