Building a custom plugin for a tool integration with Apache Ranger: Significance of pollIntervalMs

Rising Star

I have been trying to build a custom plugin for a inhouse tool that we have built for apache ranger. I have been reading various articles and found pretty good ones including the one here.

From what I understand the importance of specifying pollIntervalMs is to refresh the policies in Apache ranger admin periodically, hence without restarting Ranger admin. But when considering an example, as seen in the case of Nifi the polices are cached in a temporary directory in Nifi. Is this caching really required when developing the plugins? Is this caching done by this pollIntervalMs or is it something specific to Nifi?

@MattWho  @bbende  Any thoughts on this?
