How we built object notifications in Tigris
Tigris now supports object notifications! Object notifications are how you receive events every time something changes in a bucket. Think of it as your bucket's way of saying "Hey, something happened! Come check it out!", much like the inotify subsystem in Linux. These notifications can be helpful for keeping track of what's going on in your application.
Imagine you're building a photo-sharing app. Every time a user uploads a new picture, you want to automatically generate a thumbnail and maybe even run it through an AI to detect any inappropriate content. With object notifications, this becomes a breeze!
Now, let's pull back the curtain and see how we built this feature and a few tricky situations we had to handle. Grab your hard hat, because we're going on a little tour of Tigris's inner workings!
Tigris isn't just any object store – it's a global object store. This means that objects can be changed in multiple regions around the world. This makes them available in multiple regions, always ready when you need them. But means we need a way of keeping track of all the changes for the same object. This is where replication comes in.
