parallelizePublisher

public static <R> org.reactivestreams.Publisher<R> parallelizePublisher(IntSet segments,

Will create a publisher that parallelizes each publisher returned from the publisherFunction by executing them on the executor as needed.

Note that returned publisher will be publishing entries from the invocation of the executor. Thus any subscription will not block the thread it was invoked on, unless explicitly configured to do so.

Type Parameters:

R - the returned value

Parameters:

segments - segments to parallelize across

executor - the executor execute parallelized operations on

publisherFunction - function that creates a different publisher for each segment

Returns:

a publisher that
