I now experimented with different ideas how to implement the #lockfree #queue for multiple producers and multiple consumers. Unsurprisingly, some ideas just didn't work. One deadlocked (okaaay ... so it wasn't lockfree) and I eventually gave up trying to understand why.
The "winner" so far is only "almost lockfree", but at least slightly improves performance. Throughput is the same as with the simple locked variant, but average response times are 10 to 20% quicker (although they deviate stronger for whatever reason). Well, that's committed for now:

Not a criticism of the staff but today I've spent 4 hours in telephone queues to 3 different Council departments. I've only resolved 1 issue
Über #Schwarz ist viel zu erzählen; aber als die Architekten anfingen, alle Schwarz zu tragen, wie hier erzählt, hatte ich es aufgehört.
Als Nuance von #Grau kann ich es noch sehr gut unterbringen. Aber erstmal hab ich noch immer einen Aufsatz zu #Rosa im #Queue ,Warteschleife.
Bislang hören wir noch was über Einkaufswagen.

Phew! I need to figure out a way to get data from a Raspberry Pi into a database on a server over an unreliable network.
The data is not a stream, but there is a new data point being generated every 5 minutes.
I'm thinking I need something like a local queue on the Pi, and once Internet is there, the elements from the queue need to be transferred, one by one, then added into the database.
Rabbit hole, here I come!

Got an interesting question today about #Fedify's outgoing #queue design!
Some users noticed we create separate queue messages for each recipient inbox rather than queuing a single message and handling the splitting later. There's a good reason for this approach.
In the #fediverse, server response times vary dramatically—some respond quickly, others slowly, and some might be temporarily down. If we processed deliveries in a single task, the entire batch would be held up by the slowest server in the group.
By creating individual queue items for each recipient:
It's a classic trade-off: we generate more queue messages, but gain better resilience and user experience in return.
This is particularly important in federated networks where server behavior is unpredictable and outside our control. We'd rather optimize for making sure your posts reach their destinations as quickly as possible!
What other aspects of Fedify's design would you like to hear about? Let us know!
It's always great to see @rosa and she talked about her #SolidQueue implementation at #rubycommunityconference in #krakow.
She also gave a shout-out to @bensheldon's #goodjob and mentioned how @getajobmike's @sidekiq is blazingly fast.
Mentioned pueue task queue the other day. There's an emacs porcelain for it.

@eikedrescher Hallo Eike,
zufällig über Deine Podcast App Queue gestolpert.
Hab eine lange Podcasthistorie unter Apple:
- begonnen mit Apple Podcasts & iPod nano
- iOS und Overcast
- Pocketcasts
- dann lange Castro
- seit einem Jahr wieder Overcast
Experimentiere gerne mit Podcast Apps und Deine neue App sieht schon einmal sehr schick und minimal aus. Schon einmal ein guter Start.

Someone once noticed that the word "queue" was just Q with four unnecessary letters queued up behind it. I will never be that clever.
