Hi all, TL;DR:
Does anyone use jOOQ in some embedded IoT-context with ARM-based hardware and only few MiBs of RAM at all? Does anyone use jOOQ with e.g. Postgres/Oracle/... on some high resources server and mostly the same codebase in somer lower resources setup using less RAM, CPU-power and e.g. SQLite? Does anyone use jOOQ with GraalVM and native images? Thanks for your experiences! Background: I'm planning some special gateway to receive, store and forward telegrams from various different smart meters[1]. Such a gateway exists already and has proven to be somewhat limited, so "simply" should be replaced with a version 2, doing conceptually the same things, but with fewer technical restrictions. The important thing to note is that I already have the server to which version 1 of the gateway is sending telegrams right now. This means I'm already able to store, parse, process etc. those telegrams in various ways on the server and many of those things will exactly be needed the same for version 2 of the gateway. The important difference of course is resources: The server has multiple CPUs and GiBs of RAM, while the new gateway is some ARM-based thing with only 256 MiB of RAM currently. To make things even more complicated, one version of that gateway might(!) be powerd by battery only. Nevertheless, reusing as much of the already available code base seems to be abig benefit to me, to especially not need to develop the same complex business logic multiple times. I've already put my server with Tomcat and stuff 1:1 on some Raspi and things worked flawlessly as expected, only the RAM-limit became a problem. And that's where GraalVM native images and other downstripping becomes interesting.
