Real-Time Features With Symfony Mercure: A Production Alternative to WebSockets
Mercure is the Symfony-native protocol for server-pushed updates that handles most of what teams reach for WebSockets for—with far less operational complexity. Here is how to use it in production for live dashboards, presence, and notifications.
Vector Search in Production: pgvector vs Dedicated Vector Databases
Teams burn weeks choosing between pgvector, Pinecone, Weaviate, and Qdrant. Here's a pragmatic comparison based on real load characteristics — index size, query latency, update patterns, and cost at scale.
Symfony Messenger at Scale: Backpressure, Poison-Pill Handling, and the Rate-Limit Patterns That Save Your Database
