Importing Datasets

Importing datasets lets you reuse datasets within the same tenancy, or merge and replace content, without the need to create a dataset from scratch.

Note

From a local directory, you can import a maximum of 201 files in a dataset, and the dataset can be no more than 4.9 GB in size. If the number of files or the dataset size exceeds these values, upload the folder to Object Storage. The following formats are supported:
