SYSTEM AND METHOD FOR HANDLING IMPLICIT TRANSACTIONS IN A HYBRID CLOUD CACHE
摘要:
A system for handling Implicit transactions in a hybrid cloud cache. The hybrid cloud cache maintains folders in a metadata file system that includes a hierarchy of cached folders, and maintains a meta-file containing metadata of files and folders. The system obtains a meta-file from a cloud platform and compares that to a meta-file obtained from the hybrid cloud cache. An object associated with an Implicit metadata transaction is transferred to an internal namespace of the hybrid cloud cache if the comparison indicates that certain conditions are met. The system may perform a bottom-up traversal of the namespace and may abort the traversal if an outstanding explicit transaction for the object is present or the object exists in the cloud platform. An object may be moved to a temporary storage location if there is no explicit transaction on it and the object does not exist in the cloud platform.
