Apache Cassandra™ 10 Documentation February 16, 2012fixed threshold for marking nodes without a heartbeat as down, Cassandra uses an accrual detection mechanism to calculate a per-node threshold that takes into account network conditions, workload, or other emergency measure for preventing sudden out-of-memory (OOM) errors rather than a strategic tuning mechanism. It is most effective under light to moderate load, or read-heavy workloads. The default value of snapshots. Also, incremental backups combine with snapshots to provide a dependable, up-to-date backup mechanism. To enable incremental backups, edit the cassandra.yaml file on each node in the cluster and change0 码力 | 141 页 | 2.52 MB | 1 年前3
