Reading Group

Welcome to the DistSys Reading Group! Every week we present and discuss one distributed systems paper. We try to focus on relatively new papers, although we occasionally break this rule for some important older publications. The main objective of this group is to share knowledge through discussion. Our participants come from academia and industry and often carry a unique perspective and expertise on the subject matter.


We start each meeting with a short presentation of the paper by one of the group members. We record the presentation and later upload it to YouTube for the general audience. After the presentation, we move into a group discussion of the paper. This part is not on the record to make sure we can speak freely about the topic and the paper. However, I write a moderated discussion summary for each meeting and post it here. All the summaries are available via the “Summary” link next to the paper title. To see the archive of past meetings, scroll down to the “Past Meetings” section below.
