Abstract: A system that implements detection and reconciliation of system resource metadata for a distributed storage system is described. A node may obtain resource metadata specific to the node from another node that maintains system resource metadata for a distributed storage system. Based on the resource metadata specific to the node, a determination may be made that the node is not reconciled with the system resource metadata. A corrective operation may be performed to reconcile the node with the system resource metadata. A corrective operation may include terminating a resource, making unavailable a resource, modifying resource attributes, or sending a resource metadata update to system resource metadata for correction.

Abstract translation: 描述了实现分布式存储系统的系统资源元数据的检测和协调的系统。 节点可以从维护分布式存储系统的系统资源元数据的另一个节点获取特定于节点的资源元数据。 基于特定于节点的资源元数据，可以确定节点不与系统资源元数据协调。 可以执行校正操作以使节点与系统资源元数据协调。 纠正操作可以包括终止资源，使资源变得不可用，修改资源属性，或将资源元数据更新发送到系统资源元数据进行纠正。

Abstract: Distributed database management systems may maintain collections of items spanning multiple partitions. Index structures may correspond to items on one partition or to items on multiple partitions. Item collections and indexes may be replicated. Changes to the data maintained by the distributed database management system may result in updates to multiple index structures. The changes may be compiled into an instruction set applicable to the index structures. In-memory buffers may contain the instructions prior to transmission to affected partitions. Replication logs may be combined with an acknowledgment mechanism for reliable transmission of the instructions to the affected partitions.

Abstract translation: 分布式数据库管理系统可以维护跨越多个分区的项目的集合。 索引结构可以对应于一个分区上的项目或多个分区上的项目。 项目集合和索引可能被复制。 由分布式数据库管理系统维护的数据的更改可能会导致对多个索引结构的更新。 这些更改可以编译成适用于索引结构的指令集。 内存缓冲区可能会在传输到受影响的分区之前包含指令。 复制日志可以与确认机制组合，以将指令可靠地传输到受影响的分区。
