@andysbhai When the Redis server is shut down, all jobs in the Redis queue will be lost. Redis is an in-memory data structure store, and it doesn't persist data to disk by default. Therefore, when the Redis server is stopped, all data in memory is lost, including your queued jobs.
To avoid losing queued jobs when the Redis server is shut down, you can use Redis persistence features, such as RDB (Redis Database) or AOF (Append-Only File) to persist data to disk. RDB is a point-in-time snapshot of the Redis database, while AOF logs all write operations performed on the database.
You can configure Redis to automatically save data to disk periodically, or manually trigger a save command. When Redis restarts, it will reload the data from the persistence file, including your queued jobs.
Another option is to use a hybrid approach where you store the jobs in both Redis and a persistent database such as MySQL or PostgreSQL. This way, if Redis crashes, you can still retrieve the jobs from the persistent database.
In summary, if you want to use Redis as a queue driver, you need to consider the persistence strategy to ensure that you don't lose queued jobs when the Redis server is shut down. Redis persistence features can help to ensure data durability, or you can use a hybrid approach to store the jobs in both Redis and a persistent database.
