NiFi Unable to write flowfile content to content repository

Question

I have a simple flow which receive http requests by handlehttprequest, process it and push to Kafka. I don't have any error in processors, but I give this warning repeatedly in panel.

6 WARN [Timer-Driven Process Thread-9] o.a.n.c.repository.FileSystemRepository Unable to write flowfile content to content repository container default due to archive file size constraints; waiting for archive cleanup. Total number of files currently archived = 1198

It seems related to Content Repository Archiving, but I don't know how to solve it. Is it possible to disable archiving by nifi.content.repository.archive.enabled set to false without affecting to loss data in flow.

The Content Repo then makes the decision whether the Resource Claims should be archived or deleted (based on the value of the "nifi.content.repository.archive.enabled" property in the 'nifi.properties' file). If archiving is disabled, then the file is simply deleted from the disk. Otherwise, a background thread runs to see when archives should be deleted (based on the conditions above). This background thread keeps a list of the 10,000 oldest content claims and deletes them until below the necessary threshold.
