Executing Operations Corresponding To Target Entities Associated With File Systems

One or more non-transitory computer-readable media comprising instructions that, when executed by one or more hardware processors, cause performance of operations comprising:

• receiving, at a file system, a first request from an application for the file system to execute a first target operation corresponding to a first target entity;
• responsive at least to receiving the first request to execute the first target operation, executing, by the file system, a first logging operation comprising writing metadata to a first log entry of a first data structure stored in one or more persistent storage media;
• determining, by the file system, that execution of the first logging operation is complete;
• transmitting, from the file system to the application, a response to the first request that is based on completion of the first logging operation, the first logging operation being different than the first target operation requested by the first request;
• wherein based on receipt of the response to the first request, the application executes an application operation prior to the file system completing execution of the first target operation;
• subsequent to transmitting the response to the application:
• accessing the first log entry;
• executing the first target operation on the first target entity based at least in part on the first log entry,
• wherein executing the first target operation (a) modifies a second data structure that corresponds to the first target entity and is stored in one or more transient storage media, and (b) results in generation of an updated second data structure;
• persisting, to the one or more persistent storage media, data corresponding to the updated second data structure resulting from executing the first target operation.

A system comprising:

• at least one device including a hardware processor;
• the system being configured to perform operations comprising:
• receiving, at a file system, a first request from an application for the file system to execute a first target operation corresponding to a first target entity;
• responsive at least to receiving the first request to execute the first target operation, executing, by the file system, a first logging operation comprising writing metadata to a first log entry of a first data structure stored in one or more persistent storage media;
• determining, by the file system, that execution of the first logging operation is complete;
• transmitting, from the file system to the application, a response to the first request that is based on completion of the first logging operation, the first logging operation being different than the first target operation requested by the first request;
• wherein based on receipt of the response to the first request, the application executes an application operation prior to the file system completing execution of the first target operation;
• subsequent to transmitting the response to the application:
• accessing the first log entry;
• executing the first target operation on the first target entity based at least in part on the first log entry,
• wherein executing the first target operation (a) modifies a second data structure that corresponds to the first target entity and is stored in one or more transient storage media, and (b) results in generation of an updated second data structure;
• persisting, to the one or more persistent storage media, data corresponding to the updated second data structure resulting from executing the first target operation.
