FAST '24 - In-Memory Key-Value Store Live Migration with NetMigrate

Zeying Zhu, University of Maryland; Yibo Zhao, Boston University; Zaoxing Liu, University of Maryland

Distributed key-value stores today require frequent key-value shard migration between nodes to react to dynamic workload changes for load balancing, data locality, and service elasticity. In this paper, we propose NetMigrate, a live migration approach for in-memory key-value stores based on programmable network data planes. NetMigrate migrates shards between nodes with zero service interruption and minimal …
