Log Rotation and Retention:?

Short answer: Implement log rotation and manage log retention to prevent logs from consuming excessive disk space, while maintaining logs for troubleshooting. Example: In a Payment Service, logs should include transaction IDs, user identifiers, and payment status for better tracking of issues.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.
