In this tutorial, we build an elastic vector database simulator that mirrors how modern RAG systems shard embeddings across distributed storage nodes. We implement consistent hashing with virtual nodes to ensure balanced placement and minimal reshuffling as the system scales. We visualize the hashing ring in real time and interactively add or remove nodes to […]
Alibaba Tongyi Lab research team released ‘Zvec’, an open source, in-process vector database that targets edge and on-device retrieval workloads. It is positioned as ‘the SQLite of vector databases’ because it runs as a library inside your application and does not require any external service or daemon. It is designed for retrieval augmented generation (RAG),
If you’ve ever watched a game and wondered, “How do brands actually measure how often their logo shows up on screen?” you’re already asking an ACR question. Similarly, insights like: are all powered by Automatic Content Recognition (ACR) technology. It looks at raw audio/video and figures out what is in it without relying on filenames,
AI applications rarely deal with one clean table. They mix user profiles, chat logs, JSON metadata, embeddings, and sometimes spatial data. Most teams answer this with a patchwork of an OLTP database, a vector store, and a search engine. OceanBase released seekdb, an open source AI focused database (under the Apache 2.0 license). seekdb is
