Just over a year ago Google made all the open source code on GitHub available for querying within BigQuery and as if that wasn’t enough you can run a terabyte of queries each month for free!
When my co-founders and I first started on our startup a little over a year ago, we asked other startups about what to database they were using. Nine out of ten people all had the same response: “Just go with Mongo.”
The DeWitt clause lets database vendors forbid publishing benchmarks. What the clause is, which vendors still use it, and what you can legally publish.
Some gut-based judgements on the effectiveness of data.
AutoGPT decided to drop the support for vector databases: Pinecone, Milvus, Redis, Weaviate - all gone. What has happened to the original idea of efficiently storing agent's memories?
