[DISCUSS] JanusGraph 0.2.0 Release

[Jason Plurad]

My first time doing this, so according to the release policy docs...

I'd like to call for a code freeze in preparation for the JanusGraph 0.2.0 release. I propose the code freeze begins at Friday, September 30 at 5 PM Pacific.

Several great features have been contributed since the JanusGraph 0.1.1 release including
  * Cassandra CQL storage adapter
  * Cassandra 3 OLAP adapter
  * Elasticsearch 5 and 6 support
  * Lucene and Solr 6 and 7 support
  * Coding examples
  * Many bug fixes and documentation updates

With today's merge of the dynamic graph manager, I don't think there are any other big items outstanding that would hold up the 0.2.0 release. As discussed previously regarding the TinkerPop version, JanusGraph 0.2.0 will target Apache TinkerPop 3.2.6. The outstanding PR for TinkerPop 3.3.0 support will be at the top of the list for the next JanusGraph release.

I volunteer to be the release manager. After preparing the release artifacts, I'd expect to kick off the voting on Monday.

[Robert Dale]

Friday, September 29?

Saturday, September 30?

Great. Thanks for taking up the job, Jason. 

A couple of questions for the new features (CQL and the Cassandra 3 OLAP). Do we say they are 'new' and 'experimental' in this first release for them?  I guess it will just be what we want to say in the release notes. Also do we have good domentations for them?

Thanks,

Jerry

Excellent, thanks Jason! I'll be in and out this weekend, but if you start the packaging & prep before Monday drop me a note and I'll see if I can help, same goes if you run into issues come Monday.

Quick update. We had a nice push over the last few days to get many issues tied down, and things are in pretty good shape.

However, there are a few issues outstanding that need to be addressed:

* Cassandra version - https://github.com/JanusGraph/janusgraph/issues/585
    A few minor test case issues with CQL and newer versions. Once resolved, update version compatibility matrix.

* Solr version - https://github.com/JanusGraph/janusgraph/issues/588
    Testing against 5.2.1. If it works, update version compatibility matrix. If not, update migration notes.

* Elasticsearch migration
    * https://github.com/JanusGraph/janusgraph/issues/589 - update migration notes
    * https://github.com/JanusGraph/janusgraph/issues/591 - bug identified

Other than these known items, let's keep the code freeze intact.

I'd still be willing to accept more documentation fixes because those are always good to have. Robert published preview docs at https://robertdale.github.io/docs.janusgraph.org/0.2.0-SNAPSHOT/

[Jason Plurad]

We're getting very close!

Complete
https://github.com/JanusGraph/janusgraph/issues/588

Pull request ready
https://github.com/JanusGraph/janusgraph/issues/589
https://github.com/JanusGraph/janusgraph/issues/591

Fixed, but could use more testing
https://github.com/JanusGraph/janusgraph/issues/585

This last item is for Cassandra 3 support. If you follow along on #585, sjudeng has gotten the existing CQL test cases to pass. Still outstanding are some additional changes to enable testing against partitioners and SSL. This is more work than the other items above, so it could push out the release a bit -- let's guess one week, assuming no major issues arise as a result. There are plenty of benefits to this in terms of "certifying" that JanusGraph works with recent Cassandra releases, so I think it's worthwhile to hold up the release for it.

In the meantime, definitely welcome everybody to keep testing it out by building master from source. Docs are still open game and we can probably entertain lower impact fixes also.

If folks have strong opinions on the matter, feel free to chime in on this thread.

[Alexander Patrikalakis]

Also, I probably should add some documentation for the codepipelines module. Theoretically it’s goal is to speed up release testing.

[Jason Plurad]

Docs on codepipelines would be fantastic, Alex. Thanks!

[Ted Wilmes]

I've been doing some OLAP testing and ran into the below issue on two systems using the zip distribution. If you all agree, I think this should be fixed prior to the 0.2.0 release. I'll start taking a look at it. If someone can also reproduce the issue to make sure I'm not off-base, that'd be appreciated too.

https://github.com/JanusGraph/janusgraph/issues/605

Thanks,

Ted

[Jason Plurad]

Should the vote be in a separate thread?

[Jerry He]

I see it is in the same thread, but the subject line changed. 

Yes, it is better in a separate thread so it more prominent. 

Also, given it is a 'major' release, and it is close to the weekend, could we have more time (a week) for the community to VOTE?

Thanks,

Jerry

[Jason Plurad]

It was supposed to be a top level thread. Not sure why Gmail decided to do that to me. I’ll start another thread when I’m back at a computer. Please refrain from voting on this thread. 

As for extra time to vote, one week sounds reasonable. Did we do that for 0.1.0 also?

Yup.  0.1.0 was 7 days.

[Jason Plurad]

For those of you enjoying this as much as I am, it seems like there's some sort of bug when attempting to start a new thread by sending an email to the list. Google really wants to match it to the previous discussion, even though the subject is different. I had to start a new thread directly from https://groups.google.com/forum/#!topic/janusgraph-dev
I may have many challenges, but I really didn't think email was one :-/
