public interface SinkStage extends Stage
A pipeline stage that doesn't allow any downstream stages to be attached to it. Corresponds to a data sink.
Modifier and Type Method Description
setLocalParallelism(int localParallelism)Sets the preferred local parallelism (number of processors per Jet cluster member) this stage will configure its DAG vertices with.
setName(String name)Overrides the default name of the stage with the name you choose and returns the stage.

setLocalParallelismDescription copied from interface:
StageSets the preferred local parallelism (number of processors per Jet cluster member) this stage will configure its DAG vertices with. Jet always uses the same number of processors on each member, so the total parallelism automatically increases if another member joins the cluster.
While most stages are backed by 1 vertex, there are exceptions. If a stage uses two vertices, each of them will have the given local parallelism, so in total there will be twice as many processors per member.
The default value is -1 and it signals to Jet to figure out a default value. Jet will determine the vertex's local parallelism during job initialization from the global default and the processor meta-supplier's preferred value.

StageOverrides the default name of the stage with the name you choose and returns the stage. This can be useful for debugging purposes, to better distinguish pipeline stages in the diagnostic output.
