What Are the Core Data Collection Methods for Modern Enterprises?

Foundational Collection Approaches

API-Based Data Collection forms the backbone of modern data ecosystems. Contemporary API integration extends beyond basic REST endpoints to incorporate change data capture, automated schema evolution, and intelligent retry mechanisms. Unlike traditional polling methods, modern systems use log-based CDC to capture transactional changes with sub-second latency by serializing database changes into streaming platforms, enabling near-real-time replication without taxing source systems.

Database Replication and CDC has transitioned from niche to essential for enterprise data strategies. Log-based CDC reads database transaction logs to capture inserts, updates, and deletes with exact sequence fidelity. This approach eliminates the "frozen table" problem during snapshotting and reduces replication latency to under 500 milliseconds. However, high-frequency CDC still encounters scaling challenges with workloads exceeding 10,000 transactions per second.
