bigcache GetWithTTL not supported

[Christopher]

The bigcache implementation of GetWithTTL is just a hard coded 0 duration but with no indication in API it will not work as intended.

I suggest instead returning an error that lets the user know that the method is in fact not supported and it should not be relied upon.

Current behavior:

// GetWithTTL returns data stored from a given key and its corresponding TTL
func (s *BigcacheStore) GetWithTTL(ctx context.Context, key any) (any, time.Duration, error) {
	item, err := s.Get(ctx, key)
	return item, 0, err
}

Proposed change:

ErrNotImplemented = errors.New("Method not implemented for codec")

// GetWithTTL returns data stored from a given key and its corresponding TTL
func (s *BigcacheStore) GetWithTTL(ctx context.Context, key any) (any, time.Duration, error) {
	return nil, 0, store.ErrNotImplemented
}

Hi @melpomene,

Thank you for your feedback.

I agree that this API could be marked as not implemented and precise that the Get() method have to be use.

Please feel free to submit a pull request to change this behavior.

Thanks

BUT when chain bigcache with Redis, it broker our services.

@melpomene I think @exherb is right.

I don't have this in mind but we should keep this method implemented, whereas throwing an error.
