So, you want to deploy on the edge?
Summary: Edge computing aims to reduce latency by deploying applications closer to users, but data consistency remains a challenge. Developers must choose between dealing with cross-region latency on writes or reads. Most internet apps are read-heavy, so it's generally better to handle latency on writes. Some databases, like Turso and Litefs, forward writes to the leader while keeping reads local, optimizing for read-heavy applications. However, ensuring data consistency while minimizing latency remains a complex issue in edge computing.

Comparison of Vector Databases
Summary: This article compares well-known vector databases for semantic search and retrieval-augmented generation (RAG) applications, including Weaviate, Pinecone, pgvector, Milvus, MongoDB, Qdrant, and Chroma. The author suggests considering scalability, cost, latency, and compliance requirements when choosing a vector database. Storing embeddings where your data already lives can reduce complexity, compliance concerns, and costs.
