What are the most important resources to guarantee the performance of an etcd cluster?
To guarantee the performance of an etcd cluster, the most crucial resources are network throughput and disk I/O. This is because etcd relies heavily on network communication for consensus algorithms and data replication, and it requires fast disk I/O for writing and reading data efficiently. Adequate network throughput ensures minimal latency in data transfers between nodes, and efficient disk I/O ensures that data is written and accessed quickly, which is critical for maintaining the cluster's performance.
B is correct
https://etcd.io/docs/v3.4/op-guide/performance/
Consensus performance, especially commit latency, is limited by two physical constraints: network IO latency and disk IO latency.
should be B
It's B!
