Abstract: A block-based storage system may implement reducing durability state for a data volume. A determination may be made that storage node replicating write requests for a data volume is unavailable. In response, subsequent write requests may be processed according to a reduced durability state for the data volume such that replication for the data volume may be disabled for the storage node. Write requests may then be completed at a fewer number of storage nodes prior to acknowledging the write request as complete. Durability state for the data volume may be increase in various embodiments. A storage node may be identified and replication operations may be performed to synchronize the current data volume at the storage node with a replica of the data volume maintained at the identified storage node.

Abstract: A block-based storage system may implement dynamic durability adjustment for page cache write logging. A rate of incoming write requests for data volumes maintained at a storage node may be monitored. Based, at least in part, on the rate of incoming write requests, a dynamic modification to a durability property for a data volume may be made, such as enabling page cache write logging the data volume or disabling write logging for the data volume. When incoming write requests are received, a determination may be made as to whether page cache write logging for a particular data volume is enabled. For write requests with disabled page cache write logging, the page cache may be updated and the write request may be acknowledged without storing a log record describing the update in a page cache write log.

Abstract translation: 基于块的存储系统可以实现页面缓存写入日志记录的动态耐久性调整。 可以监视在存储节点处维护的数据卷的传入写入请求的速率。 至少部分地基于传入写入请求的速率，可以对数据卷的耐久性属性进行动态修改，例如使页面缓存写入记录数据卷或禁用数据卷的写日志记录。 当接收到进入的写入请求时，可以确定是否启用特定数据卷的页面缓存写入日志记录。 对于具有禁用页面缓存写入日志记录的写入请求，可以更新页面缓存，并且可以确认写入请求，而不将描述更新的日志记录存储在页面缓存写入日志中。
