What should you verify before replacing a Redis-style cache?
List the commands and data types your app uses, along with expiration and recovery behavior you rely on. Verify those against the Dragonfly version you would run before changing where the app connects.
How do self-hosted Dragonfly and Dragonfly Cloud differ?
Dragonfly Cloud is the managed service. For self-hosted Dragonfly from version 2.1, the vendor’s source-available terms permit production use up to an aggregate of 100 virtual CPUs without a paid license. Read the terms for your use and budget for the infrastructure you operate. Earlier releases have different terms.
What should be ready before you switch over?
Write down the old and new versions, where the original data lives and how the app behaves if cached entries disappear. If the cache is disposable, plan a refill. If values must survive, verify the supported transfer and recovery path for your versions.
Which behaviors must match before a cache switch?
On paper, list the actions a fictional menu app needs: save the menu, read it and let a short-lived copy expire. For each action, write down the expected result.
- Mark the required behaviorCircle the expiration behavior and any part of the app that assumes a stored value survives a restart.
- Choose a fallbackWrite how the app could rebuild a missing menu and what you would keep available if the new cache fails the compatibility check.
