Hey all,
In my example below I have a source queue. In the middle I have a flow that
can fail for a few different network related reason and all I want to do is
drop the request back in the top of the funnel. But I am not entirely sure
how I can get access to the element that went into the flow and caused the
failure.
val queue = Source.queue[ArchiveValidationRequest](50,
OverflowStrategy.fail)
queue.via(alwaysOnFlow).recover {
case ex: Throwable =>
error("Element failed. Reinserting back into queue to be processed")
queue.offer(???)
}
This seems like a fairly basic pattern but its not super obvious how to get
that failed request. recoverWithRetries doesn't seem to be what I want here
as I just want to capture the failed element and just try to process it
later.
