Trino workflow
Create a data source
**Duplicate data sources**: In order to avoid two data sources referencing the same table, users can not create duplicate data sources. If you attempt to create a duplicate data source using the API, you will encounter a warning stating "duplicate tables are specified in the payload."
POST /trino/handler
Save the provided connection information as a data source.
