Distributed Transactional Systems Cannot Be Fast

Diego Didona, Panagiota Fatourou, Rachid Guerraoui +2

We prove that no fully transactional system can provide fast read transactions (including read-only ones that are considered the most frequent in practice). Specifically, to achiev…

Understanding and taming SSD read performance variability: HDFS case study

María F. Borge, Florin Dinu, Willy Zwaenepoel

In this paper we analyze the influence that lower layers (file system, OS, SSD) have on HDFS' ability to extract maximum performance from SSDs on the read path. We uncover and anal…

PaRiS: Causally Consistent Transactions with Non-blocking Reads and Partial Replication

Kristina Spirovska, Diego Didona, Willy Zwaenepoel

Geo-replicated data platforms are at the backbone of several large-scale online services. Transactional Causal Consistency (TCC) is an attractive consistency level for building suc…

Limiting the Spread of Fake News on Social Media Platforms by Evaluating Users' Trustworthiness

Oana Balmau, Rachid Guerraoui, Anne-Marie Kermarrec +3

Today's social media platforms enable to spread both authentic and fake news very quickly. Some approaches have been proposed to automatically detect such "fake" news based on thei…

Distributed Transactions: Dissecting the Nightmare

Diego Didona, Rachid Guerraoui, Jingjing Wang +1

Many distributed storage systems are transactional and a lot of work has been devoted to optimizing their performance, especially the performance of read-only transactions that are…

Causal Consistency and Latency Optimality: Friend or Foe?

Diego Didona, Rachid Guerraoui, Jingjing Wang +1

Causal consistency is an attractive consistency model for replicated data stores. It is provably the strongest model that tolerates partitions, it avoids the long latencies associa…
