- The right tool for the right job, but don’t use 1000 tools.
- The art of scaling is getting done what needs to be gotten done, while staying as close to statelessness as possible, without introducing unneeded complexity by doing so.
- Hardware vendors lie, appliance vendors lie. SSDs are great, but will not save you. Vendor lock-in is the anti-scale.
- The thing is, the key to the whole thing is that finest granularity of locking. Once you have a lock deep down in your system, your whole system is a locked system. This "lock" is not a thread-lock, it could be a cross-shard-join, it is anything that is not inherently scalable.
