Google Cloud Dataflow and Weld side by side: price, connectors and features, where each one is the better choice, and what Weld replaces.
Google Cloud Dataflow
WeldAn animation of the migration. Your apps and databases sync through Google Cloud Dataflow while Weld's team maps every connector, then both run in parallel into your warehouse until the row counts match, and finally Google Cloud Dataflow is switched off while Weld keeps syncing and orchestrates the dbt run after each sync.
Google Cloud Dataflow is a fully managed batch and stream data processing service built on Apache Beam. Weld puts ingestion, transformations, orchestration and reverse ETL in one product, with 300+ connectors built in house.
You want a service native to the cloud you already run on.
You want ingestion, transformations, orchestration and reverse ETL in one product, on one bill.
