Laravel: regenerate cache

Question

I am using cache to store data structure from database:

Cache::forever(static::DATA_STRUCTURE, json_encode($tree));

However before I generate there should cleaned old:

Artisan::call('cache:clear');

But generating new cache takes some time and I want to store old cache until new will be generated.

I am using typical file cache. Does anyone can provide some hint? Maybe we can do it from the box or some package.

At this moment I see only one solution: just generate in some other folder and remove old folder with cache, then move new instead the old.

Answer 1

I solved my problem when I pushed data in variables, cleaned the cache by tag, then pushed new data to this tag.
