Method and system for updating configuration settings during the execution of an application
Provided herein are system, method, and/or computer program product embodiments and/or combinations and sub-combinations thereof for updating configuration settings during the execution of an application. In a given embodiment, a central system may read a configuration value for a configuration setting of an application from a configuration file.

assigning the configuration value of the configuration setting to a variable corresponding to the configuration setting, the variable stored in a system memory in a central system and marked as final to prevent modification by a thread in the plurality of threads;
during the execution of the application, receiving a web request to change the variable to a new configuration value; and
responsive to the web request and during the execution of the application, executing an atomic operation on the variable to change the variable to the new configuration value independent of the configuration value of the configuration setting in the configuration file, wherein the plurality of threads of the application use the variable having the new configuration value during a remainder of the execution of the application by referencing the variable in the system memory at the central system.
2. The method of claim 1 , wherein a user interface input element corresponding to the variable is displayed on a user interface.
3. The method of claim 2 , further comprising:
receiving an input with respect to the user interface input element, on the user interface, indicating the new configuration value; and
generating an instruction to execute the atomic operation on the variable to change the variable to the new configuration value based on the web request.
4. The method of claim 1 , further comprising:
receiving a new request to change a set of variables to a set of new configuration values; and
executing a new atomic operation on each variable of the set of variables to change the set of variables to the set of new configuration values in parallel, independent of the plurality of threads executed by the application.
5. The method of claim 1 , wherein the web request includes an identifier of the variable and the new configuration value.
6. The method of claim 1 , the receiving the web request further comprising:
authenticating the user with a login and password; and
responsive to the authenticating, granting access to a user interface that allows the user to generate the web request.
7. The method of claim 1 , wherein the atomic operation is a set( ) operation.
8. A system comprising:
a memory; and
at least one processor coupled to the memory, the at least one processor configured to:
responsive to an execution of an application, read a configuration value of a configuration setting of the application from a configuration file, wherein the application is one of a plurality of applications in a multi-threaded environment, wherein the application executes a plurality of threads, and wherein the configuration setting specifies a log-only-mode setting and the application uses the log-only-mode setting to determine whether to log a notification in a log file or provide the notification to a user as a live notification;
assign the configuration value of the configuration setting to a variable corresponding to the configuration setting, the variable stored in a system memory in a central system and marked as final to prevent modification by a thread in the plurality of threads;
during the execution of the application, receive a web request to change the variable to a new configuration value; and
responsive to the web request and during the execution of the application, execute an atomic operation on the variable to change the variable to the new configuration value independent of the configuration value of the configuration setting in the configuration file, wherein the plurality of threads of the application use the variable having the new configuration value during a remainder of the execution of the application by referencing the variable in the system memory at the central system.
9. The system of claim 8 , the at least one processor further configured to cause a display of a user interface input element corresponding to the variable on a user interface.
10. The system of claim 9 , the at least one processor further configured to:
generate an instruction to execute the atomic operation on the variable to change the variable to the new configuration value based on the web request, wherein an input received on the user interface input element indicates the new configuration value.
11. The system of claim 8 , the at least one processor further configured to:
receive a new request to change a set of variables to a set of new configuration values; and
execute a new atomic operation on each variable of the set of variables to change the set of variables to the set of new configuration values in parallel, independent of the plurality of threads executed by the application.
12. The system of claim 8 , wherein the web request includes an identifier of the variable and the new configuration value.
13. The system of claim 8 , wherein to receive the web request the at least one processor is further configured to:
authenticate the user with a login and password; and
responsive to the authenticating, grant access to a user interface that allows the user to generate the web request.
14. The system of claim 8 , wherein the atomic operation is a set( ) operation.
15. A non-transitory computer-readable medium having instructions stored thereon, execution of which, by one or more processors of a device, cause the one or more processors to perform operations comprising:
responsive to an execution of an application, reading a configuration value of a configuration setting of the application from a configuration file, wherein the application is one of a plurality of applications in a multi-threaded environment, wherein the application executes a plurality of threads, and wherein the configuration setting specifies a log-only-mode setting and the application uses the log-only-mode setting to determine whether to log a notification in a log file or provide the notification to a user as a live notification;
assigning the configuration value of the configuration setting to a variable corresponding to the configuration setting, the variable stored in a system memory in a central system and marked as final to prevent modification by a thread in the plurality of threads;
during the execution of the application, receiving a web request to change the variable to a new configuration value; and
responsive to the web request and during the execution of the application, executing an atomic operation on the variable to change the variable to the new configuration value independent of the configuration value of the configuration setting in the configuration file, wherein the plurality of threads of the application use the variable having the new configuration value during a remainder of the execution of the application by referencing the variable in the system memory at the central system.
