Abstract: Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.

Abstract: Techniques are disclosed for file system monitoring in a system which incrementally updates clients with what occurred in a cloud-enabled platform. In one embodiment, a method comprises, in response to an event which represents that a modification to an item has taken place on the cloud-based platform, identifying whether execution of the event is to violate any local file system rule. The method further comprises, if the execution of the event is to violate any local file system rule, buffering the event until a subsequent event arrives. The method further comprises identifying whether execution of an aggregate of the events is to violate any local file system rule.

Abstract: Techniques are disclosed for improving scalability in a system which incrementally updates remote clients with events that occurred in a cloud-enabled platform. In one embodiment, a method comprises, in response to an action from a user in the cloud-enabled platform, determining a list of events to update one or more collaborators of the user about the action. The method further comprises separating the list of events into a plurality of sub-lists of events such that each sub-list of events can be stored in a database within a designated amount of time, and further comprises storing the plurality of sub-lists of events into the database to be read by the one or more collaborators. Among other advantages, embodiments disclosed herein provide enhancement in scalability, robustness and availability for cloud-based collaboration platforms with large numbers of collaborators by incorporating mechanisms to divide-and-conquer the workload of event updates in such platforms.

Abstract: Techniques are disclosed for implementing repository redundancy in a system which incrementally updates remote clients with events that occurred in a cloud-enabled platform. In one embodiment, a method comprises comparing a local timestamp of an event with a remote timestamp of the event. The event is to be stored in a queue in a repository cluster to be read by a remote client. The method further comprises updating the local timestamp of the event if the comparing indicates that the remote timestamp is more recent than the local timestamp. Among other advantages, embodiments disclosed herein ensure that no event in an action log is missed or skipped by any of remote clients in a distributed action log framework system during a switchover from an active but failed server to a backup server, and require zero or minimal down time during the switchover, thereby providing robustness and serviceability to such system.

Abstract: Techniques are disclosed for race condition handling in a system which incrementally updates clients with what occurred in a cloud-enabled platform. In one embodiment, a method comprises, in response to an event received at a synchronization client which indicates a modification to an item, comparing a sequence identifier of the item in the event with a current sequence identifier of the item. The sequence identifier of the item can be numeric and can monotonically increase as a state of the item changes. The method further comprises, if the sequence identifier in the event is larger than the current sequence identifier of the item, determining a difference between the item's state as represented in the event and a current state of the item; and, based on the difference, generating at least one synchronization step to update the current state of the item to the item's state as represented in the event.
