Content Repository

The Content Repository holds the content for all the FlowFiles in the system. By default, it is installed in the same root installation directory as all the other repositories; however, administrators will likely want to configure it on a separate drive if available. If nothing else, it is best if the Content Repository is not on the same drive as the FlowFile Repository. In dataflows that handle a large amount of data, the Content Repository could fill up a disk and the FlowFile Repository, if also on that disk, could become corrupt. To avoid this situation, configure these repositories on different drives.




The Content Repository implementation. The default value is org.apache.nifi.controller.repository.FileSystemRepository and should only be changed with caution. To store flowfile content in memory instead of on disk (at the risk of data loss in the event of power/machine failure), set this property to org.apache.nifi.controller.repository.VolatileContentRepository.
