Flowable.concatMapEagerDelayError介绍

[英]Maps a sequence of values into Publishers and concatenates these Publishers eagerly into a single Publisher.

Eager concatenation means that once a subscriber subscribes, this operator subscribes to all of the source Publishers. The operator buffers the values emitted by these Publishers and then drains them in order, each one after the previous one completes. Backpressure: Backpressure is honored towards the downstream, however, due to the eagerness requirement, sources are subscribed to in unbounded mode and their values are queued up in an unbounded buffer. Scheduler: This method does not operate by default on a particular Scheduler.
[中]将一系列值映射到发布服务器，并将这些发布服务器连接到单个发布服务器。
即时连接意味着一旦订阅者订阅，该操作员就订阅所有源发布者。运算符缓冲这些发布服务器发出的值，然后依次将其排出，在前一个发布服务器完成后再排出。背压：背压向下游移动，但是，由于迫切需要，源以无界模式订阅，其值在无界缓冲区中排队。调度程序：默认情况下，此方法不会在特定调度程序上运行。
