New Kafka API support (0.9+)

As some of you know, we are in the process of providing a set of new Processors that uses the new Kafka API (0.9+). This is a new NAR and will live for a while along side with the old Kafka NAR. The new Processors are called PublishKafka and ConsumeKafka (specifically to emphasize the new

Re: Help Wanted

Totally makes sense. My only comment was just in regards to the fact that on that Wiki page there is no mention of looking at GH PR's. I agree that in this day and age looking to GH, may be first inclination for many. However, perhaps calling that out in the contribution guide would eliminate

They are treated with same priority, but as Oleg mentioned, the PRs do make it easier for collaborative review and has the built in integration with Travis, although currently some issues to get it consistently working. On Tue, May 3, 2016 at 11:26 AM, Suneel Marthi wrote: >

Re: Help Wanted

Totally agree on all fronts. Would seem like it makes sense for a documentation PR to be opened soon with updates to the https://cwiki.apache.org/confluence/display/NIFI/Contributor+Guide#ContributorGuide-CodeReviewProcess page to remove the ambiguity. On Tue, May 3, 2016 at 11:27 AM, Bryan

Re: Help Wanted

Andrew Regarding PR vs. Patch. This has been an ongoing discussion and i’ll let other’s to contribute to this. Basically we support both. That said, personally (and it appears to be embraced by the rest of the community) PR is the preference specifically due to the inline review/comment

Oleg, I would love to help -- couple of quick questions: The GH PR's are ~60 as you indicated, but the How To Contribute guide (Code review process -- https://cwiki.apache.org/confluence/display/NIFI/Contributor+Guide#ContributorGuide-CodeReviewProcess ) shows a JIRA list with patches available.

Guys I’d like to use this opportunity to address all members of the NiFi community hence this email is sent to both mailing lists (dev/users) While somewhat skeptical when I started 6 month ago, I have to admit that now I am very excited to observe the growth and adaption of the Apache NiFi

Yes, that is perfect. I guess I did not read them all carefully enough. Thanks. Devin On Tue, May 3, 2016 at 1:22 PM, Mark Payne wrote: > Hi Devin, > > I think the 'replaceNull' function is what you are looking for. For > example: > > ${

Re: Expression Language 'getOrDefault'

Hi Devin, I think the 'replaceNull' function is what you are looking for. For example: ${ greeting:replaceNull('hello'):length():gt(5) } You can find the documentation for this function at http://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html#replacenull
