Payment systems demand absolute data consistency, idempotency, and auditability. There is zero room for data loss.
By combining these resources with "System Design Interview Alex Xu Volume 2," you'll be well-equipped to succeed in your system design interview and take your career as a software engineer to the next level.
Push architectures (e.g., Graphite) require targets to send metrics to a central pool, which can overwhelm servers. Pull architectures (e.g., Prometheus) let the metrics collector scrape targets at its own pace, preventing cascading failures. 6.
