Stream listening cache updater

An apparatus comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
• receive, from an application on a remote user device, a request for first information associated with a user account associated with a user of the remote user device;
• determine, based on the request, whether the first information is stored in an application cache of the apparatus;
• retrieve, from a data store and based on a determination that the first information is stored in the application cache, one or more first incremental changes to the first information associated with the user account, wherein the one or more first incremental changes represent first modifications of second information, associated with the user account, stored in the data store;
• modify, based on the one or more first incremental changes, the first information in the application cache to second information;
• assign, based on the modification of the first information, a time-to-live (TTL) value to the second information;
• send, based on the modification of the first information, the second information to the application of the remote user device;
• monitor, via a listening service, a data stream for information relating to the user account;
• detect, in the data stream, a second incremental change;
• modify, based on the second incremental change, the second information to third information;
• refresh, based on the modification of the second information, the TTL value;
• receive, from the application, a request for the third information associated with the user;
• send, from the application cache to the application, the third information;
• and
• delete, at an expiration of the refreshed TTL value, the third information from the application cache.

One or more non-transitory media storing instructions that, when executed by one or more processors, cause the one or more processors to perform steps comprising:

• receiving, via an application cache and from an application on a remote user device, a request for first information associated with a user account associated with a user of the remote user device;
• determining, based on the request, whether the first information is stored in the application cache;
• retrieving, from a data store and based on a determination that the first information is stored in the application cache, a first incremental change to the first information associated with the user account, wherein the first incremental change represents a first modification of second information, associated with the user account, stored in the data store;
• modifying, based on the first incremental change, the first information in the application cache to second information;
• assigning, based on the modifying of the first information, a time-to-live (TTL) value to the second information;
• sending, based on the modifying of the first information, the second information to the application of the remote user device;
• monitoring, via a listening service, a data stream for information relating to the user account;
• detecting, in the data stream, third information;
• replacing, based on detecting, the second information with the third information;
• refreshing, based on the modifying of the second information, the TTL value;
• receiving, via the application cache and from the application, a request for the third information associated with the user;
• sending, from the application cache to the application, the third information;
• and
• deleting, at an expiration of the refreshed TTL value, the third information from the application cache.
