hey hn, supabase engineer and blogpost coauthor here. we made our first experiments with HNSW index for vector search and noticed about 5 times better performance compared to IVF w…

even networking alone adds about 1ms or so, and these are 2 hops each side: lb - sv - db, instead of the same instance for pgb scenario another 1ms goes for a gain of a millions co…

supabase engineer here would be happy to answer questions about load testing setup here is the github repo[0] with an app that helps me launch terraforms and k6 and keep track of l…

should be yes, but even in examples from openai, they usually do splitting into chunks For example in chatgpt-retrieval-plugin[0] repo default chunk size is just 200 tokens this is…

heya, supabase engineer here, i coauthored the part about benchmarking different models with pgvector to compare QPS when using fewer dims models. btw, you can find the dataset wit…

it means the precision at K(10) or precision for first 10 documents retrieved. In other words - number of relevant documents amongst retrieved 10(k) of them So 0.98 precision would…

i am not Paul of course, but i just want to highlight that the idea behind blogpost was to show that if you set some settings for postgres correctly, you can achieve much better pe…

Let me know if you want to play around with it and plug it in your ChatGPT, we can expose it if there is a need

hey hn, supabase engineer here I just added a PR to the great retrieval plugin template repo from OpenAI to add Datastore options for Supabase and Postgres. This is an implementati…

Hey, from what we’ve seen up to 50k per node should be ok for supavisor on 4 cores as well. And TPS is here mainly to demonstrate that we not only create dummy connections but that…

Hi, i was running these million connections benchmarks, happy to answer if you have any questions regarding this:) In short, that was pretty easy to do, only things we had to tweak…

I like C4 for system design overview and sequence diagrams to show detailed process of interactions in one particular scenario. I found these two the most useful for me. I also lik…
