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 the discussion. Our participants come from academia and industry and often carry a unique perspective and expertise on the subject matter.

Format

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. For the archive of the summaries, navigate to the “Past Meetings” section below.

Recent Reading Group Meetings

Reading Group. FoundationDB: A Distributed Unbundled Transactional Key Value Store

Last week we discussed the “FoundationDB: A Distributed Unbundled Transactional Key Value Store” SIGMOD’21 paper. We had a rather detailed presentation by Moustafa Maher. FoundationDB is a transactional distributed key-value store meant to serve as the “foundation” or lower layer for more comprehensive solutions. FoundationDB supports point and ranged access to keys. This is a […]

Reading Group. Evolution of Development Priorities in Key-value Stores Serving Large-scale Applications: The RocksDB Experience

On Wednesday, we had our 26th reading group meeting, discussing RocksDB with a help of a recent experience paper: “Evolution of Development Priorities in Key-value Stores Serving Large-scale Applications: The RocksDB Experience.” Single-server key-value storage systems are crucial for so many distributed systems and databases. For distributed folks like myself, these often remain black-boxes that […]

Reading Group. Unifying Timestamp with Transaction Ordering for MVCC with Decentralized Scalar Timestamp

Unlike many of my recent summarier, I will mskr this one short, I promise. “Unifying Timestamp with Transaction Ordering for MVCC with Decentralized Scalar Timestamp” NSDI’21 paper proposes a mechanism to order transactions in multi-version distributed data-stores. One of the problems with distributed transactions is the ordering required to achieve consistency. In particular, we often […]

Reading Group. Strong and Efficient Consistency with Consistency-Aware Durability

In the 62nd reading group session, we covered the “Strong and Efficient Consistency with Consistency-Aware Durability” paper from FAST’20. Jesse did an excellent presentation for the group that explains the core of the paper rather well: This paper describes a problem with many leader-based replication protocols. It specifically focuses on ZooKeper and Zab, but similar […]

Reading Group Paper List. Papers ##61-70

We have gone through our current list of papers, covering 10 interesting projects over the past 10 weeks. Now it is time to move on with a new set of papers that will carry the reading group all the way through the summer term. Conflict-free Replicated Data Types – June 16th Strong and Efficient Consistency […]
