Hello!
I've been messing around with akka-streams lately and ran into some
problems. I'm not sure where to go from this point.
I have a TCP connection to an external data feed, in which I can subscribe
to a wide variety of real-time data. What exactly will be subscribed to
changes during runtime.
Messages from the external feed can land in one or many actors, and these
actors have varying lifespans. Where the messages end up depend on their
type and different types of information inside them.
How would I do this? From what I gather, using a FlexiRoute means I cannot
add output ports after it has been materialized.
At one point the stream could look like this:
tcp io
|
transform(chop at LF)
|
map(_.utf8String)
|
map(FeedMessageParser(_)) // data is now Option(FeedMessage)
|
filter(_ != None)
|
/|\
/ | \
/ | \
/ | \
/ | \
/ | \
/ | \
TYPE=1 ID=3 TYPE=4,ID=4 // different prerequisites decide where the
data flows next
| | / \
| | / \
| | | |
| | | |
| | | |
sub1 | | |
sub2 | |
sub3 sub4
How do I do this best? Should I take a step back and look over my options,
or is there a way to tame the river?
