What is the FASTEST way to load data into an Autonomous Transaction Processing service instance?

Uploading the source file to Oracle Cloud Infrastructure Object Storage is the fastest way to load data into an Autonomous Transaction Processing service instance because this method leverages the high throughput and scalability of cloud storage. Object Storage is designed for speed and efficiency, allowing large volumes of data to be uploaded quickly and securely. From there, the Autonomous Transaction Processing (ATP) service can directly access the files stored in Object Storage, enabling a streamlined process for loading data into the database.

By utilizing Object Storage, the service avoids potential bottlenecks associated with direct database connections or data transfers from local servers, as these methods can be slower and may introduce additional steps for setup or configuration. Executing a SQL script for data import, while effective, is typically more time-consuming and requires the data to already be available in the appropriate format within the database, making the initial upload process longer compared to using Object Storage. This approach to data management allows for greater flexibility and optimizes the overall loading process in a cloud environment.
