Azure Blob Storage


The Azure Blob Storage connector performs full and incremental scans over an Azure Blob Container and will extract security, metadata, and content from each object scanned. Each scanned object will be tagged with one of three possible actions: add, update, or delete, and can be routed to any Aspire pipeline as desired.

The connector, once started, can be stopped, paused or resumed via the Scheduler Component. Typically the start job will contain all information required by the job to perform the scan. When pausing or stopping, the connector will wait until all the jobs it published have completed before updating the statistics and status of the connector.
