Distributed databases talk with @markjbrown.com
We covered:
• Scaling OUT (adding nodes) vs. UP (bigger servers)
• Why partitioning is so important
• How session-level consistency lets you read your writes without the cost of full strong consistency

Embeddings are at the heart of how an LLM works. But understanding how they work is hard.
To help, I created a simple Python Notebook that takes an array of words and plots them in a 3D graph to show how the compare in a multi-dimensional space.

At #ESPC24 @markjbrown.com is showing pretty nicely priced, low-latency vector search of 100M vectors. I'm thinking that price-wise Cosmos DB is looking pretty sharp, so at scale there will come a point where you'll want to evaluate Cosmos against your other vector DBs
