Lynceus: Cost-efficient Tuning and Provisioning of Data Analytic Jobs
Maria Casimiro, Diego Didona, Paolo Romano +3
Modern data analytic and machine learning jobs find in the cloud a natural deployment platform to satisfy their notoriously large resource requirements. Yet, to achieve cost effici…
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…
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…
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…
Okapi: Causally Consistent Geo-Replication Made Faster, Cheaper and More Available
Diego Didona, Kristina Spirovska, Willy Zwaenepoel
Okapi is a new causally consistent geo-replicated key- value store. Okapi leverages two key design choices to achieve high performance. First, it relies on hybrid logical/physical…
