Why Does a Key Disappear in Redis?
Normally, Redis keys do not disappear. If a key is missing, it may have expired, been evicted, or been deleted.
Perform the following checks one by one:
- Check whether the key has expired.
- View the monitoring information and check whether eviction was triggered.
- Run the INFO command on the server side to check whether the key has been deleted.
