The platform scans the connector configured on a subscription-based data offering every five minutes, to identify whether any new files have been added since the last scan.
The platform determines whether a new file is present in the storage connector by analyzing for each file:
- the file name,
- the file extension,
- the file hash (unique value corresponding to the file content).
A file will be identified as new only if one or more of the three elements are different from all the files already present in the data offering. In this case, the new file will be added to the data offering, and transmitted to all acquirers who have an ongoing data transaction.
In the case of an update made to a file already present in the storage connector, the file update will lead to a change in the file's hash. The file will then be identified as new by the platform, and added to the data offering.
