Adding a connection to Amazon S3 in Watson Query

Connecting to Amazon S3 in Watson Query

The Amazon S3 connector requires specific information to create a connection to it in Watson Query.

For more information, see Data sources in object storage in Watson Query.

Before you begin

To access data that is stored in Cloud Object Storage, you must create a connection to the data source where the files are located. Watson Query integrates with object storage connections and supports PARQUET (or PARQUETFILE), Optimized Row Columnar (ORC), comma-separated values (CSV), tab-separated values (TSV), and JSON data formats. All other file formats are not supported.
