Hi, Currently, the progress and completion status information is only logged and directed to a StatisticsProvider if configured. Apart from *getStats* which as you rightly pointed out makes sense when the blob store is shared there's a newly introduced *getOperationStats()* which can help but would still need a StatisticsProvider instance to be used for initialization of the GC object. There are some improvements needed for which I created OAK-7639 [1].
