Hi everybody, I am creating a daily index and set these to a specific alias and I have the doubt, is this a good practice or is there a performance problem? ---

There's no technical limit, but in practice you don't want to go absolutely crazy. They do incur a certain overhead on the master, related to updating/maintaining the cluster state. Hundreds or thousands of aliases are fine. Hundreds of thousands, millions, etc are not ok 🙂 ---
