• Armin Möbius and Sven Ulrich to create a JIRA ticket for the Cassandra writer/reader. For the integration, automatic tests are needed. The DB writer/reader tickets could serve as a template.
• To keep us everybody up-to-date regarding running study theses, please spread proposal slides, proposal documents, theses via the Kieker research mailing list.
• Andre van Hoorn will announce when the Git repository will be moved from Gitlab to GitHub. The only way to integrate changes into the master will be a merge request. "Heavy committers" will get access to the Kieker repository. For students, the default is to go via a GitHub fork and pull request.
• Next Kieker release scheduled for Oct 2016. We may decide to have it as a 2.0 version for the performance symposium (also 10th Kieker anniversary)
