Vitalii Diravka updated DRILL-6564:
-----------------------------------
Description:
Storage plugin handler can be improved with:
* Versioning can be implemented by introducing timestamp:long in the
DataChangeVersion.
Zookeper ZNode stats has timestamp values. So timestamp when
storage-plugins.conf file was created can be used in the process of updating
plugin. When timestamp of file and plugin config from PersistentStore is the
same - nothing need to do
* The approach of updating plugins configs without restarting drillbit could
be implemented.
* It can be extracted to the separate service, like Installer Agent, which can
generate _storage-plugins.conf_ files depends on the environment and system env
properties._
