Topstep’s migration journey: Self-managed Redis OSS to Amazon ElastiCache for Valkey
Topstep migrated roughly 53 million keys from a self-managed Redis OSS 7.4 instance to a fully managed, Multi-AZ Amazon ElastiCache for Valkey 7.2.6 cluster. The old setup ran on a single EC2 R5.4xlarge node with no replica, and nightly batch jobs spiked read P90 latency to approximately 250 ms. The team used RedisShake in PSYNC mode for a blue/green cutover, since their post-fork Redis 7.4 source fell outside the managed migration tool's supported range. A single Route 53 DNS change completed the cutover in seconds. Afterward, read P99 latency was about 1.25 ms and write P99 roughly 0.5 ms, with automatic Multi-AZ failover and 1 to 2 engineer-days per month freed from patching and backups.

AI in Production Without a WHERE Clause
Bối cảnh triển khai AI mà không có bước review rủi ro giống như thiếu một WHERE clause trong SQL có thể dẫn đến đêm dài khắc phục sự cố. Nguyên nhân kỹ thuật nằm ở việc các model AI có thể tạo ra dữ liệu không mong muốn khi không có bộ lọc phù hợp. Hệ quả có thể rất nghiêm trọng khi hệ thống AI vô tình tạo ra nội dung độc hại, sai lệch hoặc vi phạm chính sách. Đáng học hỏi là bài nhấn mạnh việc xác định rõ vị trí của cơ chế "phanh" (brake) trong hệ thống AI và ai chịu trách nhiệm kiểm soát nó.
Bài viết này giải thích tại sao thiếu bước kiểm duyệt trong AI sản xuất có thể dẫn đến hậu quả nghiêm trọng như lỗi query SQL không có WHERE clause.

Two migrations collide: one loud failure, one silent one
Two incompatible migrations merge clean, then resolve in the database — as a failed deploy in one environment and a healthy one in another, decided by apply order. The idempotent version is worse: every statement succeeds and the schemas silently diverge.
