Hello Everyone, In one of our project, we only have one large box available for running NiFi in production (to start with). This is due to some data center related issues (availability of space etc.). Later, if required, we will move to a multi-node cluster.
We are thinking about - Should we set up NiFi to run in Clustered mode from the beginning i.e. NCM + Slave node on single machine or should we set it up as single-node deployment. Some of the considerations are: * How difficult is it to move from single node deployment (without running NCM) to a multi-node cluster? I mean, can we simply make some configuration settings and run NCM to existing installation and add multiple nodes to it? Should we worry about any potential data/configuration loss while doing such an upgrade? * Is NCM resource intensive? * Any other factor we should consider? Thanks, Manish
