Subject Instaclustr Masters scholarship
Date Wed, 08 Feb 2017 03:24:02 GMT
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 (

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.

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

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
   - 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.
