Abstract: A distributed database management system maintains logical collections of data. The collections may grow at varying rates, and may place storage and workload processing demands on the system that change over time. A value representative of the current maximum of capacity utilization for computing nodes in the system may be calculated. An estimate of the number of days for each computing node to reach the current maximum may be calculated, and compared to an average number of days. Computing nodes whose number of days is above the average may be selected to receive new logical collections of data.

Abstract translation: 分布式数据库管理系统维护数据的逻辑集合。 集合可能以不同的速率增长，并且可能会将存储和工作负载处理需求置于随时间变化的系统上。 可以计算代表系统中计算节点的当前最大容量利用率的值。 可以计算每个计算节点达到当前最大值的天数估计值，并将其与平均天数进行比较。 可以选择天数高于平均值的计算节点来接收新的逻辑数据集合。
