Amazon CloudWatch Pipelines introduced conditional processing, enabling users to apply transformation processors only when specified rules are met, enhancing control over log data ingestion. This feature supports 21 different processors including Grok and Rename Key, allowing per-entry action application or processor-wide skipping based on conditions.
Alongside conditional processing, a new drop events processor filters out unwanted log entries from third-party sources, reducing noise and storage costs. Both capabilities are available at no extra charge in all AWS regions offering CloudWatch Pipelines, though standard ingestion and storage fees apply.
