@joehalfmen @quoll @rodhilton Complexity is a matter of perspective - distributed 10TB database is "complex" to a front-end engineer, but it's relatively boilerplate to a principal data architect.

Same thing with Twitter - it's a highly-tuned high-volume distributed system. It's "complex" to someone who doesn't know what they're looking at, like Musk.

But it's a relatively standard architecture to those who actually work in this space.
