Vibhath, There are a couple of different background processes that run within the Content Repository.
One of the processes takes any files in the repository that are not longer used by FlowFiles in the flow. It either moves them into an archive directory or deletes them (based on the value of the “nifi.content.repository.archive.enabled” property in nifi.properties). A second background process periodically runs and looks at all of the data that is in the archive/ directories. It check isf any of the files is older than the threshold (based on the “nifi.content.repository.archive.max.retention.period” property). If so, it deletes the file. This process then checks if too much of the content repository’s disk space is used up (based on how much storage space is used and the value of the “nifi.content.repository.archive.max.usage.percentage” property). If the storage space threshold is exceeded, it starts deleting the oldest data out of the archive directories until either the amount of disk space that’s in use falls below that threshold, or the archive directories are empty.
