Lantern is a Postgres extension to enable performant vector search using an index. Lantern is built using Usearch, an optimized C++ implementation of the HNSW algorithm, the most performant algorithm for vector search. In this post we discuss the significance of index creation times and how Lantern enables 90x faster index creation times than pgvector, another popular vector search Postgres extension, using external indexing. We also compare Lantern's performance against Pinecone, a popular, clo...
