well it's apples and oranges. Why do people buy F150 instead of fitting things into the trunk of a Corolla? cuz they got a lot of stuff.

For people who run thousands of QPS on billions of vectors, Milvus is a solid choice. For someone playing with a twitter demo with a few thousand vectors, any vector db can do the job well. In fact there is a fun project Milvus Lite designed for that case :)

I've seen many builders migrate from pgvector to Milvus as their apps scale. But perhaps they wish they had considered scalability earlier.

(I'm from Milvus so i could be biased.)

We regularly do tens of thousands of QPS on pgvector fine on massive data stores.

We dropped milvus after they started trying for force their zilliz garbage saas down our throats.

People buy F150s because they find them cool and not because they actually need the space. Your Corolla could make deliveries around town in roughly the same time, while being cheaper and easier compared to introducing a new expensive car. In situations you need more space (which most of us won't), you can add a trailer instead.

Interesting, I guess we're on the same page ;)
