@andreshg112 See https://github.com/GeneaLabs/laravel-model-caching#experimental-cache-cool-down-in-specific-models. It let's you turn off cache invalidation for a certain time an extremely high-traffic models that aren't critical. For example, you may not want to invalidate cache every time a comment is added, but instead only invalidate that cache every 15 minutes. This could cause comments to only appear to update every 15 minutes on the website, depending on how you decide to implement that feature.
I actually never use cache cool down. It was a feature request some time back.

If everything works as expected you do not need TTL.
After you change some data on the model itself or on the related models the cache will be devalidated automatically.

@borovaka We have some legacy code base which does not use Eloquent and Laravel at all, that's why we need TTL.

How do you think to use this package then? It is binding to the eloquent methods and properties. Are you planning to mock this methods in your legacy code?
If this is the case, you can create rememberForever method on your current entities base class and implement TTL there.

@Eke Thanks for inquiring about this. @borovaka is correct, this package is intended for Laravel use specifically. It can't really be used without Eloquent.

This would be great in my case because I have a database that is filling so fast, so I want to add a TTL in order to free space because I have to do it manually. I cannot configure a cron job right now.

@andreshg112 Could you elaborate? If configured correctly, Redis or MemCached should be managing their storage automatically, and invalidating their cache when they run out of space.
Or are you talking about you need to cull your actual database manually from time-to-time of old records, and when you do that, the cache is no longer in sync with the database?

Thanks for answering! The cache is always synced with the database. Even, we do not modify the database frequently. However, when the Redis server is full, this package cannot write to the server anymore, so we get this error:
RedisException: OOM command not allowed when used memory > 'maxmemory'.

From this midnight to this midday (12 hours), it has occupied 5.1 GB. The day the application was released, it occupied 20 GB in a few hours. That's the reason why I want to set a TTL.
The graphic below shows the max space occupied in bytes in the Redis instance in the last week in a period of six hours.

@andreshg112 Thanks for the detailed response! Let's see if we can't get your Redis server to dump cache when it runs out of space. Have you taken a look at this article: https://ma.ttias.be/redis-oom-command-not-allowed-used-memory-maxmemory/
specifically solution 2? Let me know if that doesn't work for you.
Also take a look at this article: https://aws.amazon.com/premiumsupport/knowledge-center/oom-command-not-allowed-redis/
Specifically the settings around making space by evicting the least-accessed keys.
Let me know how that goes.

I'm checking it. Thanks!
Got a question. I don't know what "cache cooldown" is. I see it a lot in the code.

I think this is gonna work. I tried it in a testing environment and everything is ok. I'll answer here if it works as expected in production.
Thank you so much!
