You can choose whether or not to apply type inference to table data imported from a database.
To enable type inference, select the Infer column data types checkbox.
Tip: To see the effects of type inference, you can toggle the checkbox and review data type listed at the top of individual columns. To override an individual column's data type, click the data type name and select a new value.
You can configure the default use of type inference at the individual connection level. For more information, see Create Connection Window.
For schematized sources that do not require connections, such as uploaded Avro files, the default setting is determined by the global setting for initial type inference. For more information, see Configure Type Inference.
