Log streams like Axiom and Datadog can be used to provide powerful querying and alerting on logs and errors from your Convex functions, helping with debugging issues when they come up and providing early insights to detect smaller issues before they become bigger. This article covers how to do the several common things with either Axiom or Datadog hooked up as a Convex log stream including filtering to a request, logging structured metadata, and visualizing usage.

Our CTO James gave a talk at Developer Week 2024 about how backends have been letting down product developers by not providing clean abstractions that empower development without introducing unnecessary complexity. James outlines four major failures of the status quo: * Bad ideas in query models * Bad ideas in type systems * Bad ideas in caching and performance * Bad ideas in data sync He explains why these exist, how they are holding back developers, and discusses recent innovations at Convex that address these four areas.

I recently built a full-stack app called notesGPT. It allows you to record a voice note, transcribes it, and extract action items and display them as action items. It’s fully open source and comes equipped with authentication, storage, vector search, action items, and is fully responsive on mobile for ease of use.

This year vector databases have sprung up like mushrooms to enable applications to retrieve context based on semantic search. A large portion of these applications have used the retrieved context to augment the ability of large language models (LLMs) in a pattern known as RAG. On November 7th OpenAI released its Assistants API, enabling the implementation of AI chat interfaces with context retrieval without needing a separate message store or vector database. Does this new API make vector databases obsolete?
