Understanding Memory Consistency Models: From Sequential Consistency to x86‑TSO and Weak Memory Models

This article explains how modern multiprocessor hardware and compiler optimizations affect program behavior, introduces memory consistency models such as sequential consistency, x86‑TSO, and ARM/POWER weak models, demonstrates their differences with litmus tests, and discusses the DRF‑SC guarantee for data‑race‑free programs.

Understanding Consistency in Distributed Transactions: Strong vs. Weak, CAP Theory, and NewSQL Approaches

This article explains the concept of consistency in distributed transactions, compares strong and weak consistency, relates it to the CAP theorem, and explores theoretical and practical approaches—including XA, NewSQL, and MVCC—to achieve stronger consistency across databases and micro‑services.

Why Eureka Chooses Weak Consistency: AP Model & Peer‑to‑Peer Sync Explained

This article explains how Eureka’s service registry achieves high availability through weak data consistency, adopts a peer‑to‑peer replication model, and resolves synchronization conflicts using timestamps and heartbeat mechanisms, all within the constraints of the CAP theorem.
