When a user submits an export request from Vaultastic, the request enters a queue of requests that are to be scheduled. A request will remain in the queue until it can be scheduled for the processing which in turn depends on the number of requests being already processed and the maximum concurrency threshold. For example, if the threshold is 5, only 5 simultaneous export requests can be running.
Once the number of requests in execution falls below the threshold, requests from the queue are scheduled for execution.
When execution on your requests starts, you will receive an intimation via mail.
The time taken for an export request to complete will depend on the size of the data to be exported. Typically, to export 3 GB of data will take 1 hour.
