US 2024/0193031 A1 · TIMED-OUT CLIENT MESSAGE REPLY QUEUEING TO REDUCE BACKEND SYSTEM CALLS

Abstract

An approach for reducing backend system calls. The approach determines if a client request, comprising a backend system call, has timed out. If the client request has timed out, then the approach generates a unique identity associated with the client request. The approach creates a fault message indicating a timeout of the client request. The approach inserts the unique identity into the fault message. The approach sends the fault message to the client as a response to the request. The approach creates a data structure comprising the unique identity, a timeout value, and a message buffer. The approach inserts the data structure into a message queue. Subsequently, a client sending a next request containing the unique identity can receive a response, from a slow responding backend server, after the timeout of the previous request without incurring the expense and overhead of another backend system call.

Dependent claims

A computer-implemented method for reducing backend system calls, the computer-implemented method comprising:

determining, by one or more processors, if a first request from a client, comprising a backend system call, has been timed out by at least one of the client or an application server;
responsive to a timeout, executing actions comprising:
generating, by the one or more processors, a first unique identity associated with the first request;
creating, by the one or more processors, a fault message indicating a timeout of the first request;
inserting, by the one or more processors, the unique identity into the fault message as a correlation identity of a response to the first request;
sending, by the one or more processors, the fault message to the client as a first response to the first request;
creating, by the one or more processors, a data structure comprising the unique identity, a timeout value, and a message buffer;
and
inserting, by the one or more processors, the data structure into a message queue.

6 more elements

A computer system for reducing backend system calls, the computer system comprising:

one or more computer processors and memory for executing program instructions;
one or more non-transitory computer readable storage media;
and
program instructions stored on the one or more non-transitory computer readable storage media, the program instructions comprising:
program instructions to determine if a first request from a client, comprising a backend system call, has been timed out by at least one of the client or an application server;
responsive to a timeout, program instructions to execute actions comprising:
program instructions to generate a first unique identity associated with the first request;
program instructions to create a fault message indicating a timeout of the first request;
program instructions to insert the unique identity into the fault message as a correlation identity of a response to the first request;
program instructions to send the fault message to the client as a first response to the first request;
program instructions to create a data structure comprising the unique identity, a timeout value, and a message buffer;
and
program instructions to insert the data structure into a message queue.
