SENDING INTERIM NOTIFICATIONS FOR NAMESPACE OPERATIONS FOR A DISTRIBUTED FILESYSTEM

摘要

The disclosed embodiments disclose techniques for sending interim notifications to clients of a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. During operation, a cloud controller receives a client request to perform a namespace operation upon a filesystem object. The cloud controller determines that it will need to contact at least one of another peer cloud controller or a cloud storage system to service the request, and sends an interim notification to the client to notify the client that the request is pending.

1. A computer-implemented method for sending interim notifications for a namespace operation to a client of a distributed filesystem, the method comprising:
collectively managing the data of the distributed filesystem using two or more cloud controllers, wherein collectively managing the data comprises storing the data for the distributed filesystem in one or more cloud storage systems, wherein the cloud controllers cache and ensure data consistency for data stored in the cloud storage systems; receiving at a first cloud controller a request from the client to perform a namespace operation upon a filesystem object; determining that the first cloud controller needs to contact at least one of a second, distinct cloud controller or a cloud storage system to service the request; and sending an interim notification to the client to notify the client that the request is pending.
