The article presents a lightweight tool to handle data consistency in RPC services during network timeouts by mocking or spying on service calls, ensuring data integrity without actual execution.
This article investigates a MySQL 8.0 TDSQL client experiencing connection interruptions during batch streaming, analyzes error 1161 (ER_NET_WRITE_INTERRUPTED) root causes in the MySQL source code, presents debugging steps with log and packet captures, and offers practical mitigation recommendations.
Network timeouts do not necessarily indicate server‑side failure; handling them with appropriate retry strategies, exponential backoff, and idempotent APIs—combined with mechanisms such as distributed locks and atomic transactions—helps maintain system stability while avoiding duplicate operations and resource exhaustion.
The article recounts a weekend on‑call incident where a Java monitoring service suffered network packet loss and a severe memory leak, leading to massive timeouts, high CPU usage, and frequent GC, and explains how the problem was diagnosed and resolved using tools such as top, jstat, jstack, jmap, and MAT.
