Harmonia: Near-Linear Scalability for Replicated Storage with In-Network Conflict Detection [article]

Hang Zhu, Zhihao Bai, Jialin Li, Ellis Michael, Dan Ports, Ion Stoica, Xin Jin
2019 arXiv   pre-print
To achieve this goal, Harmonia detects read-write conflicts in the network, which enables any replica to serve reads for objects with no pending writes.  ...  Experimental results show that Harmonia improves the throughput of these protocols by up to 10X for a replication factor of 10, providing near-linear scalability up to the limit of our testbed.  ...  Conclusion In conclusion, we present Harmonia, a new replicated storage architecture that achieves near-linear scalability and guarantees linearizability with in-network conflict detection.  ...

Invalidation-Based Protocols for Replicated Datastores [article]

Antonios Katsarakis
2021 arXiv   pre-print
Based on this insight, we draw inspiration from the multiprocessor for high-performance, strongly consistent replication in the datacenter.  ...  The multiprocessor regime uses invalidations to afford strongly consistent replication with high performance but neglects fault tolerance.  ...  Harmonia: Near-linear scalability for replicated storage with in-network conflict detection.

SOAR: Minimizing Network Utilization with Bounded In-network Computing [article]

Raz Segal, Chen Avin, Gabriel Scalosub
2021 arXiv   pre-print
We present an optimal and efficient algorithm for placing such devices in tree networks with arbitrary link rates, and further evaluate our proposed solution in various scenarios and for various tasks.  ...  State-of-the-art switches with near line rate computing and aggregation capabilities are developed to enable, e.g., acceleration and better utilization for modern applications like big data analytics,  ...  ACKNOWLEDGMENTS The authors would like to thank the anonymous reviewers and our shepherd, Shay Vargaftik, for their valuable feedback which helped improve the paper.  ...
