Multiple C++ stateless processes - single redis master instance - data syncronization

[Iranjeet Singh]

I have a C++ program whose name is say "Manager" .

This is a stateless process, so multiple instances of it can be run on single machine or different machines.

"Manager" binary manipulates some data in Redis i.e apply some operations on Redis keys.

If the two "Manager" instances  read/writes the same key, the results will be not as expected and discrepancy would be there. 

I want to assure, that the same Redis key is manipulated in a synchronized way by  "Manager" instances.

Thanks.

Redid is single-threaded so its operations are atomic. Thus if two processes try to write to the same key they will line up and last write wins.
