Hi, I'm rearchitecting a web app to perform updates only when necessary (instead of computing them all the time) on each request, I can have a global announcer and subscribers to know when to update within an image, but is there a way to have something like that but for inter-image coordination?
I'd only need to communicate the id and the class name (or a similar identifier), so on other images they'll update accordingly, and if there is an update in one image, it will notify the other images. The common data is on the database, so this is just to avoid re-reading a lot of things. Is a message queue a good fit for this? Pub/Sub? What is available in Pharo that works without having to set up a lot of things? Thanks! Esteban A. Maringolo
