Multigres Supports Listen/Notify Across Pooled Connections
The article explains how Multigres addresses the scaling limitations of Postgres's LISTEN/NOTIFY feature when using connection pooling. It details the technical challenges of decoupling session-based state from pooled backend connections to maintain consistent pub/sub functionality.
Why it matters
Efficient connection pooling is critical for high-scale database performance; this solution allows developers to maintain real-time event notification without sacrificing system throughput.
LISTEN/NOTIFY is a per-session feature, and Multigres pools connections away from clients. Here's how we keep Postgres's pub/sub working when no client owns a backend session.
