ETL Builder supports a range of input readers, and choosing the right one is the first practical design decision in a flow.
Supported reader paths
ETL Builder can read from:
- datasets already managed in the data store
- CSV files
- Excel files
- GeoJSON
- shapefiles
- GeoPackage and other supported file-backed inputs
Choosing the right input
- Use a dataset reader when the source is already managed in Tamaat.
- Use a file reader when the source is a reusable uploaded asset from File Manager.
- Use additional readers when the platform supports the source type you need.
A practical rule
If a source is likely to be reused across multiple flows, keep it well organized in File Manager or Data Store before you start building the transformation logic. Good ETL work starts with clean input ownership.
