--------------------------------
Summary: Expose names of ports from StatelessDataflowDefinition
and allow multiple extension directories
Key: NIFI-9292
URL: https://issues.apache.org/jira/browse/NIFI-9292
Project: Apache NiFi
Issue Type: Improvement
Components: NiFi Stateless
Reporter: Mark Payne
Assignee: Mark Payne
The StatelessDataflowDefinition class is generic, so it can potentially hold a
flow that is comprise of a {{byte[]}}, a {{VersionedFlowSnapshot}}, etc. But
this makes it difficult to know the names of Input Ports & Output Ports. We
currently expose the names of configured Failure Ports but should expose the
names of all Input Ports and Output Ports that are a part of the dataflow, as
well.
Additionally, in improving this configuration API, we should allow for multiple
Extensions directories to be specified. Currently, we allow for the NAR
directory to be specified, which is the location of the stateless nar itself
and supporting libraries. We also expose a configuration option for an
Extensions directory. But if there are missing extensions, the Extensions
directory is used to write those extensions when they are downloaded. This
means that we cannot mount a read-only volume that contains extensions. This
would be helpful when running in some cloud environments where we may have
access to multiple read-only directories.
