How to make sure only one Instances is putting data into Redis Caching server during pre-load process
Question
I am using CacheManager for Redis connections.
Right now, I have multiple instances running same application and connect to same Redis server.
At 8:00, application will be scheduled to do preload method to load data by using put into Redis server.
How do I make sure only one of them is writing to Redis?
Do I use lock or something else able to make that happen?
