Kotless autowarming is essentially just a cron that calls an endpoint every couple minutes to keep it in the AWS ready queue. Is my understanding of this correct?

Yep, it is a sugar for scheduler. The only difference that during auto warming Autowarm-event subscribers are fired

so should it completely handle the cold start problem?

Well, it should help. For example projects it eliminates problem almost completely under moderate load.

Not sure about “solve”, I am experimenting with GraalVM for Kotless, it would be the next step :)

Btw, if you would use Ktor it can also help. It does not use reflection, so it starts even faster than Kotless DSL (about 200-300ms)

Kotless DSL would take around 500ms for project like in examples

currently am using ktor. I do notice the cold starts but they are honestly not _that_ bad.
