Add OpenDAL as a kind of cache adapter

[Xuanwo]

Feature Request

Integrate OpenDAL as a type of cache adapter that can be used with redis/memcached/mini-moka more easier.

Describe the solution you'd like

Implement OpendalCacheAdapter like we do for #948

Describe alternatives you've considered

Not yet.

Hi @kaplanelad, in #978, we introduced storage support using opendal. This issue proposes utilizing opendal as a new cache adapter. Do you think it would be worthwhile to integrate more cache storage services through opendal, such as moka, mini_moka, memcached, and others?

@Xuanwo, I believe replacing the in-memory implementation would be a good step forward, and we should continue with just the Redis implementation rather than maintaining the rest.

However, once we are running with the OpenDAL engine, it will make things easier for users. They’ll only need to implement our cache trait with other OpenDAL drivers to extend functionality. If some other driver is not implemented in loco (like the list that you mentioned) a framework
