Boris,
Here's an idea youncould explore _today_.
Assume your dev and prod flows live in different bucket/registry instance.
Given that you are trying out NiFi 1.6, you should be able to extract the
versioned flow from DEV and process it to change the concurrency level for
PROD before committing
That is exactly what I needed. I didn’t realize back pressure could be disabled.
Thanks

Hello,
I've got a NiFi flow which:
1. Ingest archive files (tar.gz, rar and zip)
2. IdentifyMimeType of the archive
3. UnpackContent of the archive
4. Identify which of the files can be processed based on filename
The problem I've got is that a lot of processing time/content repo space is
I think you could put it under either project. Ultimately, if we go with that
approach, most (all?) of the logic/enhancement would be in the NiFi code base
during save version / import flow / change version operations, so probably best
to create it there.
Glad you are finding NiFi useful.
thanks Bryan and Kevin. I will be happy to open a jira - would it be a NiFi
jira or NiFi registry?
I like the approach that Bryan suggested.
I guess for now I will just color code the processors that need to be
changed in production.
P.S. I really, really like where NiFi is going...I've looked
Hi Boris,
Good point regarding concurrent tasks; thanks for sharing!
This is a great candidate for something that one should be able to create
environment-specific values for, as Bryan suggests. I agree we should create a
NiFi JIRA to track this enhancement.
Thanks,
Kevin

Hello,
Glad you are having success with NiFi + NiFi Registry!
You brought up an interesting point about the concurrent tasks...
I think we may want to consider making the concurrent tasks work
similar to variables, in that we capture the concurrent tasks that the
flow was developed with and
Hello NiFi community,
started using NiFi recently and fell in love with it! We run 1.6 NiFi alone
with new NiFi registry and I am trying to figure out how to promote NiFi
flow, created in VM environment to our cluster.
One of the things is "Concurrent Tasks" processor parameter. I bump it to 2
Mike,
That is basically the point of SiteToSiteProvenanceReportingTask...
you send the provenance events from reporting task back to the same
cluster, and then leverage existing processors like the ElasticSearch
processors.
Otherwise we'd get into building 100 reporting tasks for all the
various
Hi,
There is the following JIRA: https://issues.apache.org/jira/browse/NIFI-1598

Bryan,
I have a feeling you're right. This might call for a reporting task that
exports to ElasticSearch so that Kibana dashboards can be used to answer
these questions.
Thanks,
Mike

Mike,
As far as I know, Atlas is not really about "event level" lineage, it
is more about "system level" or "data set' level.
So I believe the goal of Atlas is to show how the systems are
connected and how a particular data set flows through the system.
So an example might be... NiFi pulls from
Hello,
There is a hostname() function in EL, but there is not one
specifically for the primary node.
I think this has come up before and probably makes sense, it just
hasn't been implemented yet.

Hi all,
Is there a way in nifi flows to get the primary node hostname or ip in
variable form eg: ${primary_node_hostname}.
UseCase: ListenHTTP processor running on the primary node, then I want to
set the URL dynamically like http://${primary_node_hostname}/endPoint.
Thanks,

Shawn,
Often when you have a loop you can run into problems with back pressure.
I'd try setting the back pressure limits to 0 / 0 B on one or more of the
relationships in the loop so the involved processors don't get "stuck".
