Need to restart Nifi 1.13.2 to clean content repository

jlvila — Tue, 18 May 2021 14:49:17 GMT

Dear all,

After migrating an historical flow from 1.11.4 to 1.13.2, without any changes, after a while, the limits are raised but the content repository is never cleaned. I restart nifi, and the content-repository is cleaned.

Thx for your help

I think I figured out with this issue.

I deal with very small and very huge contents, the default values for properties hereafter are not appropriate (Claim size retained ...), so I decrease drastically the values as follows:

nifi.content.claim.max.appendable.size=10 MB ==> 5MB
nifi.content.claim.max.flow.files=100 ==> 50
nifi.content.repository.archive.max.retention.period=12 hours ==> 2 hours

Until now, the platform doesn't freeze anymore.
