Hi, I am trying to use Nifi+Kafka to import multiple CSV files into my application.
*Problem statement:* Some of these CSV files are interlinked on attribute level. For example, the product CSV has a reference to Category CSV. Or, the Price CSV has a reference to Product CSV. Also, it is possible, that the Category CSV comes only once in the beginning and subsequently, product CSV comes for months. In such case, I need to store the Category CSV data in Nifi for future references. I am able to create a flow with all independent files but am not able to solve the file interlinking. *Queries:* 1. Is there any out of the box processor that can help implement this? 2. Do I need to use a DB (like mongodb) to persist data for future reference? Thanks in advance. -Mausam
