Previewing data is a way to see what the representative data might look like. The Preview feature shows a subset of possible data that the data connector can fetch from the source. Preview data is different from the actual data that is collected and stored within Treasure Data. Data preview does not represent your final data as it will exist in Treasure Data.

For certain source integrations, Treasure Data must first guess the data schema because the data is not predefined. For example, Amazon S3 and SFTP data connectors.

To get the data back in reasonable time, the preview data might not follow the parameters that you specified.

No Records to Preview

You might encounter situations in which there are no records to preview:

  • There is no data to preview for the data criteria specified

  • The API takes too long and times out and Treasure Data can’t fetch the preview data

  2. Navigate to Integrations Hub > Sources.

  3. Select the connection for which you want to preview the data.
