Google Cloud Dataflow is a serverless framework that enables automation and autoscaling of data processing. It allows users to collect, transform, enrich, and send log data from various sources to external sinks, such as Datadog. The Pub/Sub-to-Datadog Dataflow template provides a pre-built pipeline for routing logs directly from Google Cloud to Datadog, enabling efficient and scalable ingestion with reduced network overhead. This template supports batch processing and compression, allowing users to automatically process large volumes of log data without incurring excessive network costs. By using this template, users can leverage Dataflow to easily ingest logs into Datadog, view them alongside other logs, and create effective troubleshooting tools such as dashboards and alerts.
