PART 1 — Analytical Summary 🚀
Context 💼
Alejandra, an Odoo developer at KUIC, presented a practical case study at Odoo Experience on how her team significantly improved an eCommerce website’s performance by adding Redis caching. Faced with a production site powered by a heavy third‑party theme and “hacky” backend calls—where a full refactor wasn’t feasible—they pursued a pragmatic path: selectively caching expensive computations to make Odoo feel faster without disrupting business operations.
Core ideas & innovations ⚙️
After profiling with the Odoo profiler, the team found repeated heavy queries and computations to render semi‑static content. Odoo’s native t-cache directive helped but fell short: it’s per‑worker, short‑lived, and doesn’t allow custom invalidation logic. They chose Redis, an in-memory cache (RAM-based) known for single-threaded efficiency, I/O multiplexing, and optimized data structures, which together make it much faster than SSD-backed databases for reads.
They implemented a cache-aside strategy: on a request, attempt to read from cache; on a miss, fetch from the database, return the result, and populate the cache for next time. Concretely, they cached the output of Odoo’s template render function—storing the final HTML for semi‑static sections. This preserved Odoo’s normal behavior on first render while turning subsequent requests into near-instant cache hits. A simple connector (API) let Odoo talk to Redis seamlessly, with a boolean flag on templates to control what gets cached. Freshness was maintained with both manual invalidation (e.g., prices, publish status) and TTL-based automatic expiration (e.g., images). They monitored cache health via hit ratio and memory metrics using redis-cli or RedisInsight.
Beyond HTML caching, Alejandra highlighted broader Redis patterns applicable to Odoo: a distributed lock (“traffic light”) to prevent double bookings and race conditions across multiple nodes; a lightweight job queue for offloading tasks; storage for auth keys or any computed fields that are costly yet infrequently updated. She emphasized that caching complements—rather than replaces—clean code and proper data modeling.
Impact & takeaways 🧠💬
The results were compelling. The homepage improved from 1.92s to 0.79s, and the product listing page dropped from 4.83s to 0.76s—about a 71.54% performance gain. The approach delivered speed, flexibility, and control over data freshness without pausing production or rewriting the theme.
Key takeaways: - Use Redis to cache static or semi‑static outputs (e.g., rendered QWeb HTML) where reads vastly outnumber writes. - Balance freshness with speed using TTL and targeted invalidation; not all content needs real‑time accuracy. - Monitor cache hit ratio and memory usage; design cache keys and invalidation logic around real business events. - Don’t cache frequently written data; clear caches after big updates; and don’t rely on caching to fix inefficient code. - The team’s Redis connector module is currently private but potentially shareable on request.
Overall, this is a pragmatic blueprint for accelerating Odoo websites with Redis, particularly when technical debt or production constraints rule out a deep refactor. ⚙️
PART 2 — Viewpoint: Odoo Perspective
Disclaimer: AI-generated creative perspective inspired by Odoo’s vision.
Caching should serve simplicity, not complicate it. What I like here is the surgical approach: cache what’s expensive and mostly static, keep control of freshness, and observe the system. It’s very close to our philosophy—optimize the 20% that drives 80% of the impact while keeping the codebase understandable.
Integration matters. When teams wrap Redis with clear interfaces and explicit invalidation rules, Odoo stays clean and maintainable. Community patterns like cache-aside, sensible TTLs, and event-driven busting can become shared best practices that help everyone build faster, simpler experiences.

Disclaimer: AI-generated fictional commentary. Not an official corporate statement.
Redis is a standard play for web acceleration, and the gains Alejandra shows are credible. The challenge at scale is less about raw speed and more about governance: cache coherence across multiple workers, invalidation complexity, and high availability for the cache tier. Enterprises will ask about clustering, persistence modes (AOF/RDB), observability, and compliance—especially avoiding PII in caches and ensuring GDPR‑friendly retention.
From a product strategy view, this reinforces the UX advantage of tight integration. Our stacks typically pair distributed caching with managed services (e.g., Azure Cache for Redis) and built-in policies for resilience and auditing. Odoo’s approach is compelling for agility; the next step is codifying standards around cache keys, invalidation events, and incident response so performance gains remain predictable in complex deployments.
