Index creation time is a critical database metric. Learn more about how Lantern enables 90x faster index creation times than pgvector, and how Lantern compares to Pinecone.
B-tree is a structure that helps to search through great amounts of data. It was invented over 40 years ago, yet it is still employed by the majority of modern databases. Although there are newer index structures, like LSM trees, B-tree is unbeaten when handling most of the database queries.
It’s two years since we launched Mwmbl, the open source, non-profit search engine, on Boxing Day 2021. A good time to take stock of where we are and where we’re going. We’ve indexed over 100 million pages Thanks to our volunteers, who crawl the web using the Firefox extension and command line script, we’re crawling up…
Don’t confuse embeddings with memory. To build effective RAG, start with a search engine, not just a vector database.
MySQL needs little introduction. Over the last 28 years it has become one of the most widely deployed SQL databases. MySQL is primarily used for online transaction processing (OLTP) workloads, but is also deployed as a part of OLAP and queuing systems.
Introduction In this blog, we'll be going over some more advanced topics new in Postgres 16.
