Package org.apache.flink.runtime.jobgraph.forwardgroup

Interface ForwardGroup<T>

  • All Known Implementing Classes:
    JobVertexForwardGroup, StreamNodeForwardGroup
    public interface ForwardGroup<T>
    A forward group is a set of job vertices or stream nodes connected via forward edges. Parallelisms of all job vertices or stream nodes in the same ForwardGroup must be the same.

    • Method Detail

      • setParallelism

        void setParallelism​(int parallelism)
        Sets the parallelism for this forward group.
        Parameters:
        parallelism - the parallelism to set.

      • isParallelismDecided

        boolean isParallelismDecided()
        Returns if parallelism has been decided for this forward group.
        Returns:
        is parallelism decided for this forward group.

      • getParallelism

        int getParallelism()
        Returns the parallelism for this forward group.

        parallelism for this forward group.

      • setMaxParallelism

        void setMaxParallelism​(int maxParallelism)
        Sets the max parallelism for this forward group.
        Parameters:
        maxParallelism - the max parallelism to set.

      • isMaxParallelismDecided

        boolean isMaxParallelismDecided()
        Returns if max parallelism has been decided for this forward group.
        Returns:
