"I hope you come away with a new appreciation that trade-offs exist, there is no free lunch despite the implementation language or algorithms used. Optimizations exist, but you can’t optimize for everything. In distributed systems you won’t find companies or projects that state that they optimized for CAP in the CAP theorem. Equally, we can’t optimize for high throughput, low latency, low cost, high availability and high durability all at the same time. As system builders we have to choose our trade-offs, that single silver-bullet architecture is still out there, we haven’t found it yet."
