> "Pluggable shuffle service" in Flink provides an architecture which are
> unified for both streaming and batch jobs, allowing user to customize the
> process of data transfer between shuffle stages according to scenarios.
> There are already a number of implementations of "remote shuffle service" on
> Spark like [1][2][3]. Remote shuffle enables to shuffle data from/to a remote
> cluster and achieves benefits like :
> # The lifecycle of computing resource can be decoupled with shuffle data,
> once computing task is finished, idle computing nodes can be released with
> its completed shuffle data accommodated on remote shuffle cluster.
> # There is no need to reserve disk capacity for shuffle on computing nodes.
> Remote shuffle cluster serves shuffling request with better scaling ability
> and alleviates the local disk pressure on computing nodes when data skew.
> Based on "pluggable shuffle service", we build our own "remote shuffle
> service" on Flink –- Lattice, which targets to provide functionalities and
> improve performance for batch processing jobs. Basically it works as below:
> # Lattice cluster works as an independent service for shuffling request;
> # LatticeShuffleMaster extends ShuffleMaster, works inside JM and talks with
> remote Lattice cluster for shuffle resource application and shuffle data
> lifecycle management;
> # LatticeShuffleEnvironment extends ShuffleEnvironment, works inside TM and
> provides an environment for shuffling data from/to remote Lattice cluster;
> During the process of building Lattice we find some potential enhancements on
> "pluggable shuffle service". I will enumerate and create some sub JIRAs under
> this umbrella
