Postgres with QUIC
Engineers have experimented with running the PostgreSQL database protocol over the QUIC transport protocol instead of traditional TCP to reduce latency. The results showed significantly higher throughput and lower latency under heavy load compared to standard TCP connections.
Why it matters
This technical innovation could fundamentally improve database performance for distributed systems and edge computing applications.
View Full Visual Every backend engineer running Postgres at scale eventually learns the same painful lesson: connection pooling does not fix network physics. We deploy PgBouncer or PgCat, configure transaction pooling, lock down backend connections so the database doesn't run out of memory, and celebrate. But if your application or edge services sit tens of milliseconds away from your database cluster, your queries are still choking on a transport bottleneck we rarely talk about: the client-side TCP connection pool.
Recently, I ran an experiment to address this directly: running the Postgres protocol over QUIC (UDP) instead of traditional TCP . We modified PgCat to accept QUIC connections and multiplexed hundreds of virtual database streams over a tiny handful of UDP associations.
