Hi Folks ,
I was recently trying to explore the druid Kafka indexing tasks , and cam through this new word “supervisors” in druid.io documentation pages .
Can any one help me understand clearly on what are druid supervisors ?
Any thoughts in your own simple words ?
You can think of supervisor as a process whose job is to submit ingestion tasks to the middleManager.To start real time ingestion for a particular datasource, you create supervisor for that datasource.
The Supervisor has information about the kafka servers,topic name and taskcount etc.
I think a better way to understand it is to create a supervisor and see it in action.
