Efficient Protocols for Enforcing Causal Consistency in Geo-Replicated Key-Value Data Stores
Modern large-scale data platforms manage colossal amount of data, generated by the ever-increasing number of concurrent users. Geo-replicated and sharded key-value data stores play a central role when building such platforms. As the strongest consistency m ...
EPFL2020PaRiS: Causally Consistent Transactions with Non-blocking Reads and Partial Replication
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
Geo-replicated data platforms are the backbone of several large-scale online services. Transactional Causal Consistency (TCC) is an attractive consistency level for building such platforms. TCC avoids many anomalies of eventual consistency, eschews the syn ...
IEEE COMPUTER SOC2019PaRiS: Causally Consistent Transactions with Non-blocking Reads and Partial Replication
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
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 such platforms. TCC avoids many anomalies of eventual consistency, eschews the ...
2019Wren: Nonblocking Reads in a Partitioned Transactional Causally Consistent Data Store
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
Transactional Causal Consistency (TCC) extends causal consistency, the strongest consistency model compatible with availability, with interactive read-write transactions, and is therefore particularly appealing for geo-replicated platforms. This paper pres ...
2018Optimistic Causal Consistency for Geo-Replicated Key-Value Stores
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
Causal consistency is an attractive consistency model for geo-replicated data stores because it hits a sweet spot in the ease of programmability vs performance trade-off. In this paper we propose a new approach to causal consistency, which we call Optimist ...
2017Optimistic Causal Consistency for Geo-Replicated Key-Value Stores
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
In this paper we present a new approach to implementing causal consistency in geo-replicated data stores, which we call Optimistic Causal Consistency (OCC). The optimism in our approach lies in that updates from a remote data center are immediately made vi ...
Ieee Computer Soc2017Okapi : Causally Consistent Geo-Replication Made Faster, Cheaper and More Available
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
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 clocks to achieve low latency even in the presence of clock skew. Second, Oka ...
2017The design of Wren, a Fast and Scalable Transactional Causally Consistent Geo-Replicated Key-Value Store
Willy Zwaenepoel, Diego Didona, Kristina Spirovska
This paper presents the design of Wren, a new geo-replicated key-value store that achieves Transactional Causal Consistency. Wren leverages two design choices to achieve higher performance and better scalability than existing systems. First, Wren uses hybr ...
