Data Warehouse
Connect Gretel to data warehouse platforms.
Gretel workflows support connecting to the following data warehouse platforms:
Gretel data warehouse connectors can be used in Gretel Workflows to operationalize synthetic data into your data pipeline.
Overview
When reading from a data warehouse connector, the source action can extract:
an entire database, OR
selected tables from a database, OR
the results of SQL query/queries against a database.
Each time the workflow is run the source action will extract the most recent data from the source database.
When combined in a workflow, the data extracted from the {data_warehouse}_source action is used to train models and generate synthetic data with the gretel_tabular action, and can be written to an output database a {data_warehouse}_destination action.
Do not use your input data warehouse connection as an output connector. This action can result in the unintended overwriting of existing data.
