LinkedIn's user profile views created a massive read workload that pushed the limits of its existing document database, Espresso. To solve this, its team introduced Couchbase, a distributed NoSQL database, as a caching layer to reduce the read load on Espresso. They designed the caching layer to be independent of Espresso to avoid cascading failures if Couchbase experienced issues. The entire profile dataset is cached in every data center for quick access.
Various commenters write about how to learn about performance optimization better. It’s important to start with fundamentals, such as the sources of performance issues and how CPU cycles are wasted. Further techniques can be studied depending on the tech stack and use case. Concepts like parallelization, data structure optimization, and latency versus throughput are mentioned.
Big tech companies often release products with issues like unintuitive UIs, outdated code, unfixed bugs, and poor developer experience. This focus on quantity over quality stems from a prioritization of short-term stock gains driven by flashy new features, rather than investments in long-term product improvement. This strategy involves intentionally degrading product quality after establishing user dependence.
Software engineers should propose solutions, not just problems, and focus on team goals over just personal goals. Collaboration trumps code perfection. Software engineers should build relationships for influence, as building trust makes it easier to get buy-in and support for one’s ideas.
