| <p>Pegasus 不仅仅只提供简单的 key value 存储接口,我们还基于稳定性考虑,增加了许多有助于高效运维的特性。</p> |
| |
| <p>如果你刚开始使用 Pegasus,想要把已编译好的系统部署在你的机器上,你首先需要参考 <a href="config">配置管理</a>, |
| 根据环境来调整参数。然后你应该参考 <a href="deployment">集群部署</a> 将 Pegasus 搭载在你的机器集群上。</p> |
| |
| <p>在成功部署后,你应该着重观察系统运行情况,参考 <a href="monitoring">可视化监控</a> 来查看相关指标。</p> |
| |
| <p>在服务运行后,偶然的异常(可能是网络,磁盘,系统故障,潜在 Bug 导致的异常)会使集群抖动。如果造成了节点负载不均衡,你可以参照 <a href="rebalance">负载均衡</a> 进行操作。</p> |
| |
| <p>如果是随着业务量增大,超出了你的服务资源所能承受的能力,你可以参照 <a href="scale-in-out">集群扩容缩容</a> 来增加节点数。 |
| 如果有机器发生持久性的故障,你也可以参照 <a href="scale-in-out">集群扩容缩容</a> 剔除这个坏节点。 |
| 如果是机器的某个SSD盘出故障,可以参照 <a href="bad-disk">坏盘检修</a> 剔除这个坏盘。</p> |
| |
| <p>如果需要重启或升级集群,请参照 <a href="rolling-update">集群重启</a>。</p> |
| |
| <p>集群运行过程中,你需要时刻关注资源(磁盘、内存、网络)的使用情况,并及时做出运维调整,请参照 <a href="resource-management">资源管理</a>。</p> |
| |
| <p>如果业务数据量很大或者单条value很长,你可以参照 <a href="compression">数据压缩</a> 来提高磁盘利用率和提升读写性能。</p> |
| |
| <p>对一些重要的业务,你可以将相关的表定期进行 <a href="cold-backup">冷备份</a> 来保证数据安全性。冷备份的功能也常常用作于快速的大量数据迁移。</p> |
| |
| <p>对于一些极端情况,譬如元数据丢失、多个节点同时宕机,可能会造成集群数据的不一致。 |
| 如果元数据丢失,建议你参考 <a href="meta-recovery">元数据恢复</a>;对于数据备份丢失造成的不一致,建议你参考 <a href="replica-recovery">Replica数据恢复</a>。</p> |
| |
| <p>如果集群要依赖一个新的Zookeeper,需要迁移Zookeeper数据,请参考 <a href="zk-migration">Zookeeper迁移</a>。</p> |
| |
| <p>通常一个集群内会服务于许多表,所有的表都有相同的优先级,换言之,有某个表的请求量过大, |
| 其他表的服务质量就会下滑,这通常被称为 “多租户” 问题,你可以通过 <a href="throttling">流量控制</a> 满足每个表的 SLA。</p> |
| |
| <p>如果要迁移一个表的数据到另外一个表,请参考 <a href="table-migration">Table迁移</a>。</p> |
| |
| <p>表级的运维操作还包括 <a href="table-soft-delete">Table软删除</a> 、<a href="table-env">Table环境变量</a>、<a href="partition-split">Partition Split</a>、<a href="manual-compact">Manual Compact功能</a>、<a href="usage-scenario">Usage Scenario功能</a> 等。</p> |
| |
| <p>除此之外,我们还支持了 <a href="remote-commands">远程命令</a>,方便运维人员对Server进行直接控制,并提供了 <a href="http">HTTP接口</a>。</p> |
| |
| <p>我们在运维集群服务业务的过程中,也积累了很多 <a href="experiences">运维经验</a>,你可以参考。</p> |

| Apache Pegasus is an effort undergoing incubation at The Apache Software Foundation (ASF), |
| sponsored by the Apache Incubator. Incubation is required of all newly accepted projects |
| until a further review indicates that the infrastructure, communications, and decision making process |
| have stabilized in a manner consistent with other successful ASF projects. While incubation status is |
| not necessarily a reflection of the completeness or stability of the code, it does indicate that the |
| project has yet to be fully endorsed by the ASF. |
