After watched @starbuxman.joshlong.com latest instalment about youtu.be/ep8IZl8sk5A?..., I’m curious whether there will be some support for multitenancy in the ConcurrencyLimit annotation 🤔

💡 Just in case — if you're using #Embabel with @gradle.com , don't forget to add:

repositories {
maven {
url 'https://repo.spring.io/milestone'
}
}

...or enjoy hours of debugging fun™️ 🤡

💡 Didn’t add your data source manually? No problem.
Spring Debugger detects active database connections — including Testcontainers and @mongodb — and displays them in the Database tool window.

Remember ☝️, when you update your #SpringBoot application to the latest version and need to run the shell start script in Buildpacks, you must overwrite the builder to paketobuildpacks/builder-jammy-base!

But, keep updating!

A couple months ago, when @garnier.wf told me about #OpenFGA, I would said, „Naah, maybe someday”.

Now, I’ve just created my very first authorization model! So excited 🤩
