Exception Handling in Software Development: A Comprehensive Analysis

The article systematically distinguishes unrecoverable errors from recoverable exceptions and surveys five major handling strategies—global error codes, return‑value conventions, parameter‑based collectors, language‑level exception mechanisms, and OS‑level support—concluding that the optimal approach depends on performance constraints, code‑base design, and portability requirements.

Refactoring a Decade-Old Query Optimizer: Architecture, DIFF Fixes, Performance Gains, and Stability Improvements

Tencent engineers completely rewrote a ten‑year‑old query optimizer, shrinking the codebase by 80% and replacing its monolithic thread‑pool with a tRPC‑Fiber DAG scheduler, which cut latency by 28%, reduced startup time to five minutes, saved 40 GB memory, boosted throughput 12%, fixed numerous stability bugs, raised test coverage above 60%, and accelerated new‑feature lead time to under a day.
