Etcd的性能主要取决于磁盘的读写性能,每次数据提交分离,follow节点都必须落盘后才回复leader节点。Etcd提供了etcd_disk_wal_fsync_duration_seconds_bucket(wal日志同步磁盘耗时)和etcd_disk_backend_commit_duration_seconds_bucket(数据提交写入耗时)。为了避免常委效应,这两个指标通常使用分位指标告警。如果0.99分位的wal...

对于非结构化的数据存储系统来说,LIST 操作通常都是非常重量级的,不仅占用大量的 磁盘 IO、网络带宽和 CPU,而且会影响同时间段的其他请求(尤其是响应延迟要求极高的 选主请求),是集群稳定性的一大杀手。 例如,对于 Ceph 对象存储来说,每个 LIST bucket 请求都需要去多个磁盘中捞出这个 bucket 的全部数据;不仅自身...
