Pentaho Data Integration and Weld side by side: price, connectors and features, where each one is the better choice, and what Weld replaces.
Pentaho Data Integration
WeldAn animation of the migration. Your apps and databases sync through Pentaho Data Integration while Weld's team maps every connector, then both run in parallel into your warehouse until the row counts match, and finally Pentaho Data Integration is switched off while Weld keeps syncing and orchestrates the dbt run after each sync.
Pentaho Data Integration (PDI), also known as Kettle, is an open-source ETL tool from Hitachi Vantara. Weld puts ingestion, transformations, orchestration and reverse ETL in one product, with 300+ connectors built in house.
You need self-hosted and on-premise deployment, where Weld runs in the cloud only.
You want ingestion, transformations, orchestration and reverse ETL in one product, on one bill.
To cover what Weld does, a team running Pentaho Data Integration adds another tool, each set up and monitored on its own.
