Mark Payne updated NIFI-1527: ----------------------------- Attachment: 0001-NIFI-1527-Ensure-that-we-increment-Claimant-Counts-f.patch > Resource Claim counts not incremented on restart for FlowFiles that are > swapped out > ----------------------------------------------------------------------------------- > > Key: NIFI-1527 > URL: https://issues.apache.org/jira/browse/NIFI-1527 > Project: Apache NiFi > Issue Type: Bug > Components: Core Framework > Reporter: Mark Payne > Assignee: Mark Payne > Priority: Blocker > Fix For: 0.5.1 > > Attachments: > 0001-NIFI-1527-Ensure-that-we-increment-Claimant-Counts-f.patch, > 0001-NIFI-1527-Ensure-that-we-increment-Claimant-Counts-f.patch > > > When NiFi starts, it tallies the count of how many FlowFiles reference each > Resource Claim and then removes or archives any file in the Content > Repository for which there is no claim. > However, the claim counts are not incremented for data that is swapped out. > As a result, the content repository could delete or archive data on restart > that it should not. This could potentially result in data loss, if NiFi is > restarted while both of the following conditions are met: > * All FlowFiles that reference a Resource Claim are swapped out > * Content Repository's archive is disabled, or the archival threshold is > already exceeded from data outside of the Content Repository -- This message was sent by Atlassian JIRA (v6.3.4#6332)
