A Feature Store, or Just a Warehouse Table?

I’ll give it a few years until MLflow dominates the model package format space, with alternatives like SageMaker models fading away, and sharing pure weights becoming an arcane art. But until that dominance is absolute, I’ve been thinking that there’s another quite obvious way to package models: just store them as wheels. Packaging == persisting...

In my view, neither performance nor trying to be Python-aligned is what sets uv apart. Don’t get me wrong — try switching from uv to Poetry, and you’ll quickly notice how sluggish it (poetry) feels. uv goes extra miles to adhere to PEPs, and IMHO it’s the go-to package manager for Python these days. But these aren’t the features that surprised me...

For the past few months, I’ve been exploring Go. Having done quite a bit of grueling work shaving off milliseconds from Python web apps, I’ve found Go to be incredible. You can schedule dirt cheap concurrent operations — simply by adding go in front of a function call — and achieve true parallelism across cores.

I have always been intrigued by Bloom filters. They are very similar to hash sets but somehow consume much less memory. Sometimes, they can yield false positives, creating a peculiar tradeoff.

The Walrus operator, formally the assignment expressions, has been for some time around now in Python (since 3.8). I’ve grown fond of it :).
