Trade-offs Framework¶

The distributed-systems trade-offs that decide what a system can promise under partition and load.

Topics¶

#	Topic	What you'll learn
01	CAP Theorem	Why you can't have consistency, availability, and partition tolerance at once.
02	PACELC	The trade-off CAP omits: latency vs. consistency even with no partition.
03	Consistency vs Availability	Choose a side deliberately for a given operation, not the whole system.
04	Consistency Models	Strong, eventual, causal, and the guarantees each actually gives you.

Each topic has four depth levels — junior → middle → senior → professional — plus an interview Q&A bank. Start at your level and climb.
