Description

We noticed that two Data Node periodicals are running in a Server instance, and they are executed every two seconds.

1. DataNodeConfigurationPeriodical

This polls the certificate_exchange for new certificates. The exchange is usually empty, so it's fast. I was just wondering if this is supposed to run on every node or just Data Node? The class name suggests Data Node only.

2. DataNodeCertRenewalPeriodical

This periodical checks every two seconds if certificates need to be renewed. When it runs, it reads the keystone from the disk. That seems pretty excessive. Does this need to run every two seconds? And same as above, this is also supposed to run on a server node?
