I have the following issue.
I integrate with Google Pub Sub using Alpakka. It works flawlessly when I work with Google Cloud Pub Sub.
However, for the developers machines I want to integrate with Google Pub Sub Emulator. Obviously this is also perfectly supported by Alpakka.
The only issue I have is the really high CPU usage of the local Google Pub Sub Emulator (I run it in the Docker container).
I think this is the result of continuous HTTP pulling from the
I see in the
GooglePubSubSource that it pulls the API constantly if no messages are fetched.
fetch function here:
On my side I wrap the
GooglePubSub source in
RestartSource. I tried to throttle on my side on this source but it does not help.
To be able to use Alpakka Google Pub Sub at all I need to decrease the CPU usage on developers machines.
Do you have any suggestions?
I would really appreciate it.
