The Amazon S3 connector for CRM Analytics and Salesforce Data Pipelines uses a schema_sample.csv file to define data column types. Although the documentation specifies that no data from this sample file is uploaded, data was being uploaded to customer orgs prior to the Spring ‘26 release.
The data from schema_sample.csv is no longer uploaded, and the feature now behaves as expected.
