Artifact Description:

This is the artifact for the FAST '24 paper "ELECT: Enabling Erasure Coding Tiering for LSM-tree-based Storage". ELECT is a distributed tiered KV store that enables replication and erasure coding tiering.

For more detailed documentation, please refer to the README of the ELECT repository.

Reproducibility status:

This artifact was evaluated by USENIX FAST 2024 Artifact Evaluation Committee members and awarded all 3 Artifact-Evaluation badges: Artifacts Available, Artifacts Functional, and Results Reproduced.

Experiment:

Testbed

As a distributed KV store, ELECT requires a cluster of machines to run. With the default erasure coding parameters (i.e., [n,k]==[6,4]), ELECT requires a minimum of 6 machines as the storage nodes. In addition, we require a server node as the cold tier to store the cold data. We also need a client node to run the YCSB benchmark tool. Therefore, we require at least eight machines to reproduce the evaluations.

Detailed Instructions

Please refer to our artifact evaluation instructions to run the evaluations as in our paper.
