@Soumya Ghosh 1. The DistibuteMapCacheServer (DMC server) has not direct linkage to a dataflow built in NiFi. Thus when creating a template of your flow from NiFi for the purpose of generating your MiNiFi yaml file, the DMC Server will not be included in the template. Only the DMC client service will be included. I have not tried to manually add the DMC server to the yaml file, but is likely possible. MiNiFi does not have a rest-api where you can send command to add additional components like you can do it NiFi. 2. The only way to host a DMC server is via a NIFi instance. There is not way to execute a NAR file. 3. A major limitation to using the DMC server is lack of HA. If the NiFi instance hosting the DMC server crashes you lost all your cached data (assuming crash is not recoverable. The recommended path is to configure you ListFile processor to use one of the other available external cache server that offer HA capability. These alternate cache service are setup independent of NiFi or MiNiFi and will offer you what you need to support using Entity tracking in your ListFile processor running on MiNiFi.

@TRACEY JACKSON NiFi processors are configurable to run using a Timer Driven or Cron Driven scheduling strategy. This scheduling can uniquely configured per each processors configuration. Processors are then started and the operate based on the configured scheduler from that point forward. - The NiFi API can be used to perform any action a user can perform directly from the UI. The best way to learn the rest-api calls is to use the "Developer tools" available via most browsers. - While focused on tab where NiFi UI is open, launch the developers tools. Chrome Browser example: Then perform the action via the NiFi UI and you will see the "Network" call display in list. You can right click on that call and select "Copy as curl". Now you have an example of how to execute that same request via command line. - For more info in the NIFi rest-api, you can look in "help" found within the NiFi UI Global menu (upper right corner). The Rest Api documentation can be found in the "Developer" section at bottom of list on far left side of help UI. - The danger with trying to "run" dataflows in NiFi via command line is you may end up stopping processors in the dataflow chain that results in FlowFile being unprocessed and sitting on connection queues between processors. - Thank you, Matt - If you found this answer addressed your question, please take a moment to login in and click the "ACCEPT" link. ...
