Thursday 5th - 12nd September

I have finished reading another paper, ‘Debugging a Distributed System’ by Hector Garcia-Molina, Frank Germano, JR and Walter H. Kohler. This paper discussed the issues involved in debugging a distributed computing system and the difference between debugging a distributed system and debugging a sequential system. Different debugging techniques for distributed systems are also introduced. The debugging tools for producing and examining traces, for controlled system execution, and for monitoring, are presented.

Tim wanted me to redo my mid-year presentation at Kiwiplan next week. I’ve been practicing and preparing for it this week, since I have forgotten most of it. The presentation is scheduled next Monday.

Today I did the presentation at Kiwiplan and I got some feedback from Tim. Tim suggested that I should look deeper into the interceptor interface and see exactly how this interceptor interacts with the queries. He also suggested that I should do a logger to list all the steps that the interceptor goes through in order to intercept a query and return its information. In practice, this logger will also be useful to programmers, since it records all the important steps and the attributes that we are interested in, such as time taken for the query to process.
