Subject Re: [VOTE] Heron to enter Apache Incubator
Date Fri, 23 Jun 2017 17:07:59 GMT
"*"We believe that
having Heron at Apache will help further the growth of the streaming
compute community, as well as encourage cooperation and developer cross
pollination with other Apache projects."

I realize that each incubator proposal has a statement like this. What I am
saying is entering the incubator technically is moving source code, moving
mailing lists, etc. The act of moving does not encourage participation
directly. In the case of Heron, the majority of people that know of
big-data-streaming likely know that Heron exists. In the ASF there is
already Apex, KafkaStreams, Spark, Storm, Beam, probably 3 others I can not
remember.

Diversity is not a requirement, but in the end I believe it is what will
make long term success. Over time even large successful projects change
hands, there committers move onto other challenges and entities that prop
them up initially often reallocate resources.

"Your concerns are valid and should be addressed during incubation (ensuring
cross project collaboration, building more diversity, ...)"

Right. I am not suggesting you have the answers upfront, no one knows what
the future holds. However having some plan of attack is something I would
suggest, code sharing, integration with other tools, a creative plan new
committer outreach.  "Move it to ASF and make a tweet or a press release"
happens once. :)
