dtest commit id in CI builds

[Aleksandr Sorokoumov]

Hello,

I have been checking out recently some of the dtest-related issues and wanted 
to share an idea. It might be useful to see dtest’s commit id in the Jenkins 
logs. AFAIK Jenkins clones dtest master right now.
For example, it would be a bit easier to tackle some issues like 
CASSANDRA-13140 because one can immediately reproduce it with the same version 
of the dtest used in the build and after that reason about the changes between 
this revision and the master using git history for the particular test.

What do you think?

Best regards,
Aleksandr Sorokoumov

May be you should ask them? We are not involved in the CockroachDB github
website.

... and by the way, it is far from being the only wrong stuff in their

Deeper inside there is a diagram:

https://raw.githubusercontent.com/cockroachdb/cockroach/master/docs/media/sql-nosql-newsql.png

They compare to NoSQL along with Riak, HBase and Cassandra. 

Of course you CAN have a Cassandra cluster which is not fully available with 
loss of a dc nor consistent. 

Marketing 😊

Seriously that was over the line.   You may very well feel that the posts
are unnecessary and I am sure there are folks who would agree with you, but
let's not get nasty about it.

Re: Why does CockroachDB github website say Cassandra has no Availability on datacenter failure?

[James Carman]

I think folks might agree that it's not worth the time to worry about what
they say.  The ASF isn't a commercial entity, so we don't worry about
market share or anything.  Sure, it's not cool for folks to say misleading
or downright false statements about Cassandra, but we can't police the
internet.  We would be better served focusing on what we can control, which
is Cassandra, making it the best NoSQL database it can be.  Perhaps you
should write a blog post showing Cassandra survive a failure and we can
link to it from the Cassandra site.

Now, this doesn't apply to trademarks, as the PMC is responsible for
"defending" its marks.

I did not had the time to look into your problem yet.
Could you open a JIRA ticket to be sure that we do not forget about this
problem? I will look into it as soon as I can.

Re: AW: Why does CockroachDB github website say Cassandra has noAvailability on datacenter failure?

[Amit Trivedi]

It indeed is a marketing gimmick. By clubbing Cassandra with likes of HBase 
that favors consistency over availability, points under cons section are all 
true, just not true when applied to any one database from that group.

Thanks and Regards

Amit Trivedi

(sorry for previous blank reply..)

Please create a JIRA and it can be assigned to me. `mshuler` is my JIRA
user.

LOL They took down that image finally!! But I would still keep an eye on
what kind of fake benchmarks they might come up with.

Instaclustr Masters scholarship

[Ben Bromhead]

As part of our commitment to contributing back to the Apache Cassandra open
source project and the wider community we are always looking for ways we
can foster knowledge sharing and improve usability of Cassandra itself. One
of the ways we have done so previously was to open up our internal builds
and versions of Cassandra (https://github.com/instaclustr/cassandra).

We have also been looking at a few novel or outside the box ways we can
further contribute back to the community. As such, we are sponsoring a
masters project in conjunction with the Australian based University of
Canberra. Instaclustr’s staff will be available to provide advice and
feedback to the successful candidate.

*Scope*
Distributed database systems are relatively new technology compared to
traditional relational databases. Distributed advantages provide
significant advantages in terms of reliability and scalability but often at
a cost of increased complexity. This complexity presents challenges for
testing of these systems to prove correct operation across all possible
system states. The scope of this masters scholarship is to use the Apache
Cassandra repair process as an example to consider and improve available
approaches to distributed database systems testing.

The repair process in Cassandra is a scheduled process that runs to ensure
the multiple copies of each piece of data that is maintained by Cassandra
are kept synchronised. Correct operation of repairs has been an ongoing
challenge for the Cassandra project partly due to the difficulty in
designing and developing  comprehensive automated tests for this
functionality.

The expected scope of this project is to:

   - survey and understand the existing testing framework available as part
   of the Cassandra project, particularly as it pertains to testing repairs
   - consider, research and develop enhanced approaches to testing of
   repairs
   - submit any successful approaches to the Apache Cassandra project for
   feedback and inclusion in the project code base

Australia is a pretty great place to advance your education and is
welcoming of foreign students.

We are also open to sponsoring a PhD project with a more in depth focus for
the right candidate.

For more details please don't hesitate to get in touch with myself or reach
out to i...@instaclustr.com.

Cheers

Ben
