All, I had a few general questions regarding Clustering, and was looking for any sort of advice or best-practices information --
- documentation discusses failure handling primarily from a NiFi crash scenario, but I don't recall seeing any information on entire node-failure scenarios. Is there a way that this is supposed to be handled? - at what point should we expect pain in scaling? I am particularly concerned about the all-to-all relationship that seems to exist if you connect a cluster RPG to itself, as all nodes need to distribute all data to all other nodes. We have been also been having some issues when things are not as responsive as NiFi would like -- namely, the UI seems to get very upset and crash - do UI actions (incl read-only) require delegation to all nodes underneath? I suspect this is the case as otherwise you wouldn't be able to determine queue sizes? - is there a way to have a cluster with heterogeneous node sizes? Thanks in advance!
