What can your app save in Valkey?
Keep a quick copy of something your app can rebuild, such as a public list of available classes. Decide when entries expire and what your app does when a copy is missing. The database that holds the real bookings can stay separate.
Will entries still be there after a restart?
That depends on your setup. Valkey offers point-in-time snapshots, a log of writes, or no persistence. Each option changes what can be recovered. If Valkey holds only disposable copies, document where the app reads the original instead.
Does an open-source license mean it costs nothing to run?
The BSD license covers the software. Budget separately for memory, the machine, backups where needed and maintenance, or compare a hosted plan. Your app still needs a rule to count requests and respond when a limit is reached.
How does an empty cache recover a class listing?
Draw an empty Valkey cache and a fictional database listing three classes. Follow the first reader from the empty copy to the original list.
- Fill the copyDraw the app reading the database, displaying the list and saving a short-lived copy.
- Remove an old entryMark one class canceled in the database. Decide how the app clears or replaces the copy before it can keep showing the old list.
