Talks scheduled thus far:

Session:
Robust Communication Mechanisms in zanox Reporting Systems

It happened an annoying number of times that we wanted to improve only one particular component in our distributed reporting system, but often had to update almost everything due to the RPC version-mismatch, which occurred in a communication between the updated component and the rest of our system. To mitigate this problem and to significantly simplify the integration of new components, we extended the used RPC protocol to perform a version handshake before the actual communication starts. This RPC extension is accompanied with serialisation/deserialization methods, which are downward compatible due to being able to successfully deserialise any
serialised older version of exchanged objects. Putting together these extensions makes it possible for us to successfully operate multiple versions of frontend and backend components, and to have the power to autonomously decide what and when should be updated/improved in our distributed reporting system.


Two other talks are planned and I will provide you with further information soon.

A big Thank You goes to Immobilien Scout GmbH for providing the venue at no cost for our event and for sponsoring the videotaping of the presentations.

Looking forward to seeing you in Berlin,

David
