Background jobs for Kemal server in Crystal lang
I have a sam.cr task in place that helps me with local develpment. I tweaked make sam dev to spin up two Sentry runners, and it continues to work seamlessly with both development executables + livereload (livecompile?) again.

What language do you use for performant web jobs and services?
it seems many big web projects (rails, django, etc. GIL langs) chose go(lang) to write "services" that could be separated. Yet, just about any language with quick startup, quick execution, concurrent (and/or parallel!), garbage-collecter would work: lisps, ocaml, haxe, nim, crystal, CLI langs, JVM langs! I wonder what HN folks used. Was it a good choice?
i was specifically thinking about crystal for rails, as i noticed a few interesting repos: mosquito, a job scheduler; fruit-juice, a ruby gem to enqueue jobs into mosquito (especially from rails); and lavinMQ, a successor of rabbitMQ(?).

Background jobs for Kemal server in Crystal lang
The Crytal Sidekiq port was a tempting option for a background task runner, but I went with mosquito-cr/mosquito. My initializer looks like this:

Database for Kemal server in Crystal lang
I actually already have this implemented with the mosquito shard, but that will be covered in the next post of this series. I'm waiting for at least a day's worth of leaderboard match data to reliably compare with the results above, so stay tuned if interested I guess.
What are some alternatives?
When comparing sam and mosquito you can also consider the following projects:
