@upgradingdave if you haven't read it, Designing Data Intensive Applications has a nice chapter on encoding formats and an overview of the relative tradeoffs for performance and evolution of an API. I don't recall if Transit is even mentioned, but it helps in asking the right questions and framing a discussion about pros and cons.

"Designing data intensive applications" is far and away the most comprehensive look at the software design ecosystem that i know of. If anyone can recommend something like it i would love to know. For some reason i have read the first 8 chapters several times and im just now finally getting around to the last 2.

my copy arrived last week, I'm buzzed to read it 😄
