--------------------------------
Summary: Make Write-Ahead Provenance Repository the default
implementation
Key: NIFI-5482
URL: https://issues.apache.org/jira/browse/NIFI-5482
Project: Apache NiFi
Issue Type: Improvement
Components: Configuration
Reporter: Mark Payne
Fix For: 1.8.0
The default implementation for the Provenance Repository is the
PersistentProvenanceRepository. The WriteAheadProvenanceRepository was added in
version 1.2.0 of NiFi. We left the default as the
PersistentProvenanceRepository only because it had been heavily tested over
years of production use. Since then, the WriteAheadProvenanceRepository has
proven to be not only significantly faster but also more stable and easier to
maintain. When problems arise with the PersistentProvenanceRepository, the
solution almost always is to change to the WriteAheadProvenanceRepository.
Given this, we should now change the default implementation to be the
WriteAheadProvenanceRepository.
This involves changing the default value in the POM of nifi-resources and also
updating the Admin Guide to note the new default and review the guide for any
other wording that may need to be updated.
