> Running datastore command to retrieve the index binaries blob IDs from Azure with following options:
> {code}
> 16.06.2021 20:49:50.452 *INFO* [main] o.a.j.oak.run.DataStoreCommand - Command line arguments used for datastore command [--dump-ref --out-dir /opt/out_dir --azureds /DataStore.config --verboseRootPath /oak:index/ --verbosePathInclusionRegex /*/:data,/*/:suggest-data --verbose] 
> 16.06.2021 20:49:50.454 *INFO* [main] o.a.j.oak.run.DataStoreCommand - System properties and vm options passed [-Dsegment.timeout.interval=60, -Dsegment.timeout.execution=325] 
> {code}
> can sometimes take minutes. This operation is usually fast(a few seconds).
> The log of the command only displays little info about what is happening:
> {code}
> 16.06.2021 20:49:50.839 *INFO* [pool-3-thread-1] o.a.j.o.plugins.blob.FileCache - Cache built with [0] files from file system in [0] seconds 
> 16.06.2021 20:54:45.901 *INFO* [main] o.a.j.oak.run.DataStoreCommand - Starting dump of blob references by traversing 
> {code}
> There is no information on where the 5 minutes is spent. It could be a network hiccup, maybe Azure connectivity issues, or too many sessions opened, but there is no way to find out. We should add extra logging in _org.apache.jackrabbit.oak.run.DataStoreCommand_ in order to be able to investigate such slowness cases.
