@lru_cache vs redis-simple-cache in Python

[@AnyFactor]

It's a thankless job uploading content in the intermediate programming niche. Not many subs, not many views. But those who are watching appreciate your effort.

KZbin's been nice to me lately with recommendations. Fingers crossed.

[@10e999]

To see a Python KZbin video about actual programming tradeoffs and not just some basic syntax features is like a breath of fresh air! Thanks for your content. Subscribe.

[@modsoul]

Agreed. This is a fantastic content. 1st video i've seen from him and subscribed

Nice and quick explanation! I can actually see Redis being used as a L2 cache, maybe. A decorator that implements something like @functools.lru_cache as L1 cache and @redis_cache.cache_it as L2 would be amazing!

[@JackofSome]

That ... sounds awesome.

As an alternative solution for persistent caching I recommend the DiskCache library. It caches to the file system, so it has slightly different pros and cons compared with redis, but it's quite performant. In addition to a cache decorator it provides a bunch of other useful utilities and can be used in multi-process applications.

Hey thanks for the recommendation. I'll check it out!

[@ponysmallhorse]

Finally I found channel that can actually show me something interesting about python. It has been so long:) Big like on the video.

[@JackofSome]

Thanks for the kind words.

​@@JackofSome Have a question to fellow Experienced Pythonista, how do you feel about Classes in Python? Do you feel like most of the time we can do away with classes? I swear when I read code(which is most of my day) I feel like I can delete 90% of classes and write code in more clear and readable way without them. Problem is that All of my colleagues came from C# and Java and is an up hill battle to make them adapt to best features of Python(They basically still think in Java or C#\++).

[@JackofSome]

There's a great talk by the name of "stop writing classes" that I recommend you watch. I have similar feelings, though maybe not 90 percent. A fair bit of my code is class-less and it's better because of it. The rest I feel is better with classes.

[@ponysmallhorse]

@@JackofSome Exactly the talk that I watched back in 2015 that put me on this path. Right now I think I might went a bit overboard with this, due to interfaces of my libs are classless(and stateless for that matter) and for some people who need to use them I think it might be harder to grasp. Oh well. Great to know there are like mind people out there:)

[@JackofSome]

You can always make a wrapper class 😉

I came from recommindations and I love the straight forward content, no intro, outro, just cs You earned a new subscriber

[@nabarundev5092]

Cool stuff. You should add your 5 amazing python libraries video to the python playlist.

[@JohnHollowell]

One other huge benefit of redis is not just a cache that persists between running the same program, but a fleet of concurrently running processes that can have a shared cache. Not only does the computation results of one process get shared with all the other processes, but memory demands are reduced using a shared cache rather than several duplicate caches.

[@notreallyasloth]

🎉🎉🎉🎉 thank u I was looking for sneering exactly like this

[@UrbanGT]

Makes sense, thanks :)

[@marka9473]

I love this video

[@JackofSome]

This video loves you.

[@emmanvries]

Still, 1.3 seconds... why is redis that slow? (Despite modern computing hardware, etc)

[@JackofSome]

It's not Redis being slow, it's the serialization and IPC overhead for a several hundred megabyte data structure.
