Running service

[zzkww]

The long-term storage I use now is S3. When I run ./pravega-controller and ./pravega-segmentstore in the k8s environment, I can see it under the corresponding bucket in my S3 account, _system/containers/_sysjournal.epoch61 .container0.file2 and other types of files, why is this?

Pravega stores its own internal data and metadata in _system folder.
_sysjournal* one of such internal journal file.
