Redis is known for being a very fast data store. And as developers, who doesn't want the fastest data store? The far more complicated question is: when is Redis the right choice for a data store? Let's take a look at some project aspects that could help determine when a use case might work well with Redis.
If your entire dataset can fit into memory, then Redis may be a good choice. Using Redis in this scenario should drastically limit (or possibly eliminate) latency due to disk I/O.
In looking at your intended dataset objectively, what would happen if it was lost? If your tenant application is simply caching data that is helpful, but not necessarily mission-critical, then Redis might be a good solution.
