---------------------------------
Summary: Add DetectDuplicateUsingHBase processor
Key: NIFI-3644
URL: https://issues.apache.org/jira/browse/NIFI-3644
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Bjorn Olsen
Priority: Minor
The DetectDuplicate processor makes use of a distributed map cache for
maintaining a list of unique file identifiers (such as hashes).
The distributed map cache functionality could be provided by an HBase table,
which then allows for reliably storing a huge volume of file identifiers and
auditing information. The downside of this approach is of course that HBase is
required.
Storing the unique file identifiers in a reliable, query-able manner along with
some audit information is of benefit to several use cases.
