摘要： In one embodiment, a user or client device is connected to a distributed file system comprised of one or more physical nodes. The data on each of the physical nodes store metadata about files and directories within the file system. Some of the embodiments permit a user to take a snapshot of data stored on the file system. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories. In one embodiment, previous versions of a file or directory are stored only in response to a request to modify the file or directory. The system creates and updates a snapshot tracking data structure which provides information regarding each file or directory governed by the snapshot that was modified or deleted after the snapshot was taken. The snapshot tracking data structure may be used by the system to perform functions related to the snapshot, including deleting the snapshot.

摘要： Embodiments of the invention relate generally to incremental computing. Specifically, embodiments of the invention include systems and methods that provide for the concurrent processing of multiple, incremental changes to a data value while at the same time monitoring and/or enforcing threshold values for that data value. For example, a method is provided that determines whether multiple incremental changes to a data field could pass a threshold based on keeping track of a possible value range for the data field.
摘要翻译： 本发明的实施例一般涉及增量计算。 具体地，本发明的实施例包括提供对数据值的多个增量改变的并发处理的系统和方法，同时监视和/或执行该数据值的阈值。 例如，提供了一种方法，其确定对数据字段的多个增量更改是否可以通过基于跟踪数据字段的可能值范围来通过阈值的方法。
