Meituan Database Attack‑Defense Practice: Kernel Observability, Full SQL, and Index Optimization

Meituan’s database attack‑defense practice builds kernel observability using wait‑time quantification, captures every SQL statement directly from the MySQL kernel with lock‑free storage and Snappy compression, classifies remediation actions as lossless or lossy, and implements a multi‑layered index recommendation and governance framework that automates risk review, real‑time detection, and post‑execution optimization.
