Common Misconceptions in Distributed System Design and Their Solutions

Designing distributed systems often falls prey to misconceptions such as assuming reliable networks, zero latency, unlimited bandwidth, inherent security, static topology, zero transmission cost, and full autonomy, but applying retries, idempotency, message queues, encryption, dynamic discovery, caching, and time protocols can mitigate these issues.

Extending Paxos with Partially Ordered rnd Values for Transactional Mutual Exclusion

The article explains how Paxos can be generalized by defining its round number (rnd) over any partially ordered set, enabling both forced and non‑forced conflict exclusion mechanisms similar to 2PC, and showing how this expands Paxos’s applicability to multi‑dimensional transaction ordering and simplifies distributed database architectures.
