Continuous file metadata refresh for file gateway

A system, comprising:

• one or more processors;
• and
• memory that stores computer-executable instructions that, as a result of being executed, cause the one or more processors to:
• obtain event data corresponding to a data storage partition of a data storage service, wherein the event data indicates a plurality of entries indicative of operations performed on a plurality of data objects stored in the data storage partition;
• determine a set of data objects of the plurality of data objects identified in a directory maintained locally by a client device;
• filter the event data to produce filtered event data, wherein filtering the event data comprises removing non-redundant entries of the plurality of entries not corresponding to the set of data objects;
• and
• store the filtered event data, wherein the filtered event data, as a result of being accessed by the client device, causes an application programming interface of the client device to update the directory maintained by the client device using the filtered event data to produce a modified directory.

A non-transitory computer-readable storage medium storing thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:

• obtain an event log corresponding to a logical data container of a data storage service, wherein the event log comprises a plurality of entries indicative of operations performed on a plurality of data objects stored in the logical data container;
• identify a set of data objects of the plurality of data objects identified in a directory maintained by a client device;
• filter the event log to remove entries of the plurality of entries not corresponding to the set of data objects, wherein at least some of the removed entries comprise entries that are not redundant to other entries associated with the event log;
• and
• store the filtered event log, wherein the filtered event log, as a result of being accessed by the client device, causes the client device to update the directory maintained by the client device using the filtered event log to produce a modified directory.
