Asynchronous Counting Gate

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 a first request for permission for a first thread, executing a first task that comprises accessing a computing resource, to access the computing resource;
• responsive to receiving the first request, determining if a permit count that measures a number of permitted accesses to the computing resource meets a permit limit that restricts the number of permitted accesses to the computing resource;
• based, at least in part, on determining that the permit count meets the permit limit, returning, to the first thread, a first data structure corresponding to the first request;
• and
• subsequent to returning the first data structure, determining that at least one criterion for terminating the first request without successfully completing the first request is satisfied,
• wherein the first thread is not blocked from performing other operations during a time period between (a) returning the first data structure and (b) determining that the at least one criterion is satisfied.

A system comprising:

• one or more hardware processors;
• one or more non-transitory computer-readable media;
• and
• program instructions stored on the one or more non-transitory computer-readable media that, when executed by the one or more hardware processors, cause the system to perform operations comprising:
• receiving a first request for permission for a first thread, executing a first task that comprises accessing a computing resource, to access the computing resource;
• responsive to receiving the first request, determining if a permit count that measures a number of permitted accesses to the computing resource meets a permit limit that restricts the number of permitted accesses to the computing resource;
• based, at least in part, on determining that the permit count meets the permit limit, returning, to the first thread, a first data structure corresponding to the first request;
• and
• subsequent to returning the first data structure, determining that at least one criterion for terminating the first request without successfully completing the first request is satisfied,
• wherein the first thread is not blocked from performing other operations during a time period between (a) returning the first data structure and (b) determining that the at least one criterion is satisfied.
