I was at Yahoo almost a decade ago, when vector search within Vespa was first being rolled out in production use cases. It was already serving similarity search requests for Flickr back then.

Even though I'm with Zilliz/Milvus now, I wholeheartedly support and recommend folks check out and try Vespa. Congrats to the Vespa team!

EDIT: For folks on Twitter, you should follow Jo (https://twitter.com/jobergum) from Vespa if you aren't already. Great combo of technical content, hot takes, and vector database memes!



Huge congratulations to JKB, Frode, Kim, and the rest of the Vespa team! We are infinitely grateful for all of your help and advice. We are lucky enough to have Vespa as the foundation for our developer-focused enterprise search product.

Having worked with both Solr and Elastic in past search companies, it’s incredible to be able to deploy into Fortune 50 enterprises without any doubts about stability and with all the benefits of a cutting-edge hybrid engine.

Can’t wait to watch you on the next leg of your journey!

The Atolio team


Thank you for the shout-out Frank!


Off topic... looking forward to more engineers moving to Mastodon. I have Twitter/X blocked at DNS level and still fairly frequently encounter interesting accounts that I can't check out.


Every time I see Twitter/X here, I want to say this.


How is it other people’s problem that you block a site that they’re on?

(Fwiw I have Twitter blocked too, though not for moral reasons)


Nobody's saying it's anybody else's problem - they're just looking forward to more content being on Mastodon (or elsewhwere) as people move away from X.


, in response to a thread sharing the Twitter profile of a key person mentioned in the article, who also comments here.

The subtext is clearly “jkb, please move to Mastodon cause I blocked Twitter”. Not spelling that out doesn’t make it a lot less weird IMO.


It's not that weird, you are reading too much into the subtext. The web is in a transitory state, platforms change, people move. Wishing for more content to be available on a specific platform without blaming the author is an acceptable comment in my view.


Is there a particular mastodon server or set of servers that the engineering community is favoring? I know it technically doesn’t matter in a federated network, but curious anyway.


I'm on fosstodon. floss.social is also big.


any resource for one to learn on vector search? any textbook or whitepaper recommendations?

I am learning lsh right now and find it fascinating


We have a "Vector Database 101" series that covers vector search and vector indexes as well: https://zilliz.com/learn/what-is-vector-database

I've been meaning to dive into SCaNN and DiskANN as well, but haven't gotten around to it yet.

quick TLDR on both vs HNSW?


any ideas what do cloud providers like pinecone user underneath ?


I'm from Pinecone. We use proprietary indexes. We could've used HNSW but decided the high memory consumption (ie, costly at scale) and slow index updates (ie, data gets stale) won't cut it for production use cases.


Oh I read a lot of HNSW stuff on your/Pinecone blog series. (Great learning resource btw, well done!) So I assumed you were using HNSW already. It's a news to me that you don't use it.
