Flowable.concatMapCompletable介绍

[英]Maps the upstream items into CompletableSources and subscribes to them one after the other completes.

Backpressure: The operator expects the upstream to support backpressure. If this Flowable violates the rule, the operator will signal a MissingBackpressureException. Scheduler: concatMapCompletable does not operate by default on a particular Scheduler.
