There are some upload limits when you create a file-based data offering:
Volume limit: 10 GB per file
There is no restriction on the number of files added to an offering. When multiple files are added, they are queued. Import time may vary according to file weight and quantity. Files are transmitted to acquirers as soon as they have been imported.
Some subscription plans can include a limit on the total volume for all files within an organization’s data offerings.
For .csv, .xls, .xlsx, and .ods files, diagnostics and sample generation are only done for files under 500 MB.
