Quick clarification about Lecture 7 (Eventual consistency)

Written on 30.04.25 by Deepak Garg

Hi all,

A clarification about today's lecture: In the Bayou design, the information stored in lieu of truncated log entries is a list of the (Lamport) timestamps of the last discarded update from each replica. For the example on lecture slides 20 and 21, the entry is [-, 2,1] because all updates from P1 are still in the log (the '-' in the first position), the last discarded update from P2 is D with P2's local timestamp 2 (the '2' in the second position) and the last discarded update from P3 is E with P3's local timestamp 1 (the '1' in the third position). This is also explained on the lecture slides linked from the schedule page, and in the Bayou paper.

Hi all,

Some of you have asked about the course policy for cases where you have to miss an in-class quiz for an important reason. The policy is listed below and is also available on the course main page now.

"If you have to miss a class with a quiz for an important reason, inform the TAs at least two days before the class. Include the reason. The TAs will work out an alternative arrangement with you. If you do not inform the TAs two days in advance, you will not get any points for that project stage. If you fall sick on the day of a quiz unexpectedly, contact the TAs after you recover and produce a doctor's note to work out an alternative arrangement."

In particular, if you will miss the class this coming Monday (1st quiz), inform the TAs at the latest by tomorrow (26.04). Include the reason for missing the class.
