What you'll learn
- Consistency Models in Distributed Systems. The common misconception is that consistency) in distributed systems is the same property as ACID consistency — it is not. ACID consistency (C) is about state transition validity…
- Causal vs. Linearizable Consistency. Causal consistency preserves only the order imposed by happens-before relations; linearizability additionally bounds every operation to its real-time interval, making the system…
Questions this study answers
- Given PACELC, if a system chooses to minimize latency during normal operation, what does it necessarily sacrifice, and which point on the consistency spectrum does that decision push it toward?
- If two clients write to the same key with no causal dependency between them, which model — causal consistency or linearizability — guarantees that all readers observe those writes in the same order, and why?
