Liveliness community/future

[Maarten Koopmans]

Hi,

I have the feeling that the list is becoming more and more quiet and
that te community is not that lively. This worries me a bit.... Is it
becasue Voldemort just works, or is it because people use Cassandra or
MongoDB instead - depending on their use case?

Having said that, Voldemort "just works", so I personally don't
understand why it isn't as widely popular as Cassandra seems to
be(come).

What can we do to change this, if it is needed at all?

Best, Maarten

In my case (here at Gilt Groupe) it just works. Really works.

Hi Maarten,

I started a similar thread back in October:

https://groups.google.com/group/project-voldemort/browse_thread/thread/5b2f6331e329590e/e5f6f9349a6e8299

There was a NoSQL series a couple of weeks ago in Mountain View that
spanned four nights. The last night was scheduled to feature Voldemort,
so I had planned to go. At the last minute they swapped it with
Cassandra based on interest.

I agree that it's worrisome to see so little interaction outside of the
core committers at LinkedIn. (I'd made that point a few months ago on
the list.) Obviously Voldemort just works because LinkedIn keeps rolling
out features that sit on top of it.

One problem is that Cassandra, Riak, et al. have companies whose sole
interest is to promote those products. LinkedIn's gratefully open
sourced the project for us, but that's obviously not their
bread-and-butter, so there's little to no evangelism there.

If you have suggestions to improve things, let us know :)

Thanks!
Kirk

Few observations:

1. Voldemort "just works", Yes.
It an awesome app, I having been working on it to understand how it (distributed systems in general) works for my master's project, and it's really awesome. Clean code, great support.

2. Does it describe it self in detail, No.
I find dearth of information about it, as compared to Cassandra. Most of the helpful documentation is here but, I see people go to project voldemort homepage, which I feel is not as detailed and in-depth as cassandra's homepage.

3. Meetups? None.
I am in the Bay area and I have attended many NoSQL meeting, but none of them actually talks about Voldemort. It would be great if LinkedIn gives a talk about Voldemort. Engaging a community is equally important if you want mass adoption and interest as Cassandra. When I say, I am working on Voldemort, many people haven't even heard about it.

I've actually presented at several of the NoSQL events (most recently
at the NoSQL track at Devoxx 2010, I will also be giving a
presentation in the industrial track of ICDE 2011), but it's
impossible for us to present at every occasion. Presentations involve
work and it's non-trivial to balance this work with development, bug
fixing/debugging and production planning.

If others are interested in presenting at particular events I'd love
to help them (with existing presentation slide decks). Local user
groups and meetups are a great place to present: please don't hesitate
to reach out if you'd like to do a presentation and need material.

I also know of several upcoming presentations (e.g., Sunny Gleason
talking about his work on the use of InnoDB/HailDB with Voldemort at
ConFoo: < http://confoo.ca/en/2011/session/accelerating-nosql-running-voldemort-on-haildb
>), it might be helpful if anyone is planning to present to announce
their talks on this list.

We're actually doing a fairly heavy amount of work on Voldemort at
LinkedIn at the moment, a great deal of it being related to recently
introduced multi datacenter support (presently in use at LinkedIn).
Use of Voldemort at LinkedIn, while already extensive, is still
expanding.

Pending completion of several important bug fixes (including
integration of several patches to dynamic cluster membership aka
rebalancing from Nokia), I'd like to make a "general availability"
release of Voldemort 0.90. Of course *all* of our work is available on
github, with the most current sources in the master branch and the
candidate release in release-090 branch.

Thanks,
- Alex

Hi Alex,

Would it be possible to put InMobi on the 'powered by' page [1]? Also,
can we have a link on the main project-voldemort.com web site that
points to the 'powered by' page?

Thanks,
Kirk

Sure,

Mendeley is another, but unfortunately, I can't find any presentations
from them.

I do have the site for Mendeley, but what is the URL for InMobi?

Thanks,

Hey,

I'm the guy behind Voldemort's use at Mendeley and, repeating what others have said, I've found compared to other "nosql" databases I've used it really does Just Work, the only one I've never had a problem with.

We're over at www.mendeley.com and we're trying to start opening up what we do more from the dev side with a new site soon. In the past I've mentioned we use it before in a talk at a Hadoop users group on HBase and gave a lightning talk about Voldemort read-only stores a few weeks ago. You can find these here :-

http://lanyrd.com/2010/huguk7/ (Brief mention)

http://lanyrd.com/2011/huguk-february/scmzk/ (Lightning talk)

I'll add the latter to the presentations page, and also add a little bit about Mendeley on the Powered By page.

I am going to try and carry on giving talks about Mendeley and what we use so would love to try and push Voldemort more as I do this.

Thanks,

Dan

Hi Alex,

I don't have a URL in which InMobi speaks of their usage of Voldemort
other than the informal mention of it in the referenced tweet.

Thanks,
Kirk
