The RunFlowMarkLogic processor supports running a MarkLogic Data Hub flow and returning the result as a new FlowFile. The flow is expected to run non-ingestion steps, where data has already been ingested into MarkLogic and needs to be reprocessed via a Data Hub flow.
In order to support running a Data Hub flow, the connector must depend on a particular version of the Data Hub Java API. As of the 6.1.1 release of the Data Hub Java API, there is not a guarantee that the Data Hub Java API will work with any release of Data Hub other than its own. It is therefore recommended to ensure that the version of Data Hub you have installed in MarkLogic is the same as that of the MarkLogic NiFi connector release that you are using.
The table below lists the MarkLogic NiFi connector releases and the associated Data Hub Java API version:
| Connector version | Data Hub Java API version |
|---|---|
| 1.27.0 | 6.1.1 |
| 1.24.2 | 5.8.1 |
| 1.16.3.1 | 5.7.2 |
| 1.15.3.2 | 5.4.4 |
| 1.9.1.7 | 5.4.2 |
Please see the Data Hub documentation for roles for which roles a MarkLogic user will need in order to run a flow.
