Systems and methods for providing notifications of changes in a cloud-based file system

A cloud storage system, comprising:

• a memory;
• and
• a processor, coupled to the memory, to:
• receive, from a networked device, a subscription request to obtain information pertaining to a modification of a data file by a user device of a user that has permission to modify the data file that is stored on the cloud storage system, wherein the subscription request identifies the networked device and one or more modification actions to the data file by the user device that prompt a notification of the modification to the data file to be generated for the network device, wherein the one or more modification actions to the data file comprise at least one of generating the data file, accessing the data file, deleting the data file, or changing content of the data file;
• receive, from the user device of the user, an authorization of the networked device to subscribe to receive the notification of the modification to the data file, wherein the authorization identifies the networked device, which is different from the user device;
• record the authorization;
• determine whether the networked device identified in the subscription request is identified in the recorded authorization;
• responsive to determining that the networked device identified in the subscription request is identified in the recorded authorization, record a subscription based on the subscription request, wherein the subscription identifies the networked device as having subscribed to receive the notification of the modifications to the data file responsive to satisfaction of the one or more modification actions to the data file by the user device;
• identify an action performed to the data file by the user device of the user;
• responsive to determining that the action performed by the user device of the user corresponds to at least one of the one or more modification actions to the data file identified in the subscription, transmit to the networked device the notification of the modification to the data file;
• and
• responsive to a satisfaction of one or more predetermined criteria, delete the recorded subscription, wherein the one or more predetermined criteria comprise a failure to receive a message from the networked device within a predetermined amount of time subsequent to the transmission of the notification to the networked device.

A non-transitory computer-readable medium comprising instructions, which when executed by a processor, cause the processor to perform operations comprising:

• receiving, from a networked device, a subscription request to obtain information pertaining to a modification of a data file by a user device of a user that has permission to modify the data file that is stored at a cloud-based file system, wherein the subscription request identifies the networked device and one or more modification actions to the data file by the user device that prompt a notification of the modification to the data file to be generated for the network device, wherein the one or more modification actions to the data file comprise at least one of generating the data file, accessing the data file, deleting the data file, or changing content of the data file;
• receiving, from the user device the user, an authorization of the networked device to subscribe to receive the notification of the modification to the data file, wherein the authorization identifies the networked device, which is different from the user device;
• recording the authorization;
• determining whether the networked device identified in the subscription request is identified in the recorded authorization;
• responsive to determining that the networked device identified in the subscription request is identified in the recorded authorization, recording a subscription based on the subscription request, wherein the subscription identifies the networked device as having subscribed to receive the notification of the modification to the data file responsive to satisfaction of the one or more modification actions to the data file by the user device;
• identifying an action performed to the data file by the user device of the user;
• responsive to determining that the action performed by the user device of the user corresponds to at least one of the one or more modification actions to the data file identified in the subscription, transmitting to the networked device the notification of the modification to the data file;
• and
• responsive to a satisfaction of one or more predetermined criteria, deleting the recorded subscription, wherein the one or more predetermined criteria comprise a failure to receive a message from the networked device within a predetermined amount of time subsequent to the transmission of the notification to the networked device.
