can we make scala cache key as generic object instead of string?

Hi,
I have recently using scala cache in my application. I have a key as an object. I have to explicitly define the string as a key from the same object. can we make it generic and then it's up to the user to define it as a string or object. is there anything I am missing?

I haven't dived it the code myself, but using stringly keys is probably a compromise here. If we allowed generic object, the the redis/memcached which are remote, probably wouldn't be possible to implement since you'll need to serialize the keys somehow. You would need some type, that is generally serializable, independent of the cache implementation, and string is a straight forward one.

There may be other alternatives...

do we have a tightly coupled contract between all the implementations?

As far as I understand this is a planned future change. I actually just made a pull request to address this.
