[jira] [Created] (NIFI-3644) Add DetectDuplicateUsingHBase processor

Bjorn Olsen created NIFI-3644:
---------------------------------

             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.
