A data platform that performs a file existence check is provided. The data platform creates a bounded page and selects a set of selected metadata files from a set of metadata files, where each selected metadata file includes a set of data file metadata files. Each member of the set of data file metadata files includes a file name of a respective data file. The data platform stores the set of data file metadata files of each selected metadata file in a first sorted list in the bounded page. The data platform retrieves a second sorted list of file names of a set of data files stored on a data storage system. The data platform determines the existence of each respective data file of each member of the set of data file metadata files on the data storage system by comparing the first sorted list to the second sorted list.

File existence checks using list API

A server set may provide a document service to various clients in view of considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and assigning the respective document ranges to an agent that is deployed to at least one assigned server. A request to apply an operation to a selected document may be fulfilled by identifying the document range of the document; identifying a selected server of the server set that hosts the agent to which the range is assigned; and forwarding the request to the selected server. In some variations, servers may retain detailed information about neighboring servers (e.g., according to logical and/or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.

Elastically scalable document-oriented storage services

A server set may provide a document service to one or more clients, and may be configured to do so in view of various considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and configuring respective servers of the server set to host one or more agents to which are respectively assigned one or more document ranges. A request for an operation involving at least one document may be routed to a server hosting an agent managing the document ranges of the documents involved in the operation. Moreover, respective servers may retain detailed information about neighboring servers (e.g., according to a logical or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.
