Honestly I'd use CloudWatch Timed Events to kick off a Lambda or ECS Fargate job (which of course you can write in Clojure) assuming you're using AWS yourself anyway. If you don't care about batching maybe even just attach a Lambda to the write-to-S3 bucket itself instead of checking every 15m?
If you want to do it in-process, my tool of choice is ztellman's manifold: https://github.com/ztellman/manifold/blob/d67a8c1b9f1268c094895d70dbbf146521f5774b/src/manifold/time.clj On Mon, Dec 17, 2018 at 1:54 PM <lawrence.krub...@gmail.com> wrote: > I'm coming back to Clojure development after a year away.
