> Key: NIFI-3644
> URL: https://issues.apache.org/jira/browse/NIFI-3644
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Bjorn Olsen
> Assignee: Bryan Bende
> Priority: Minor
> Fix For: 1.3.0
>
>
> 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.
