Architecture note for Twitter API v2 filtered stream: requirements, minimal HTTP/2 design, trust boundaries, operational checks, failure modes, and conditions that would change the design.
Enabling HTTP/2 in NGINX is a one-line config change, but it shifts TLS negotiation, per-connection memory, and CPU profile. Here's the minimal setup, verification steps, and the trade-offs to monitor in production.
Learn how to turn on HTTP/2 in NGINX, tweak its settings for real‑world traffic, and measure the impact with curl and wrk. A hands‑on guide for performance‑hungry developers.
Bidirectional gRPC streaming keeps one HTTP/2 connection open for two-way messages, but idle timeouts can close it silently.
HTTP/1.1 forces browsers to open multiple TCP connections and suffer head-of-line blocking. Tomcat's NIO2 connector can multiplex HTTP/2 streams over one TLS connection—if you configure it correctly.
Enable HTTP/2 in Apache Tomcat using the Http2Protocol connector, TLS, and Java 11+, then verify with curl and browser DevTools.
