Monitoring service for pre-cached data modification
The described technology is generally directed towards detecting and propagating changes that affect information maintained in a cache. Data may be pre-cached in advance of its actual need, however such data can change, including in various different source locations. A change monitoring/signaling service detects relevant changes and publishes change events to downstream listeners, including to a cache population service that updates pre-cache data as needed in view of such data changes. Per-user-specific data also may be pre-cached, such as when a user logs into a data service.
1. A system comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
receiving a message associated with an event, wherein the message comprises a type of the event and a data item associated with the event; and
in response to determining that the event invalidates a first graph of user interface navigation elements pre-populated in a cache for anticipated future access, wherein the first graph of user interface navigation elements is associated with a user that interacts with a user interface menu comprising user interface navigation elements:
generating a second graph of user interface navigation elements corresponding to the event,
invalidating the first graph in the cache, and
pre-populating the cache with the second graph for the anticipated future access.
2. The system of claim 1 , wherein the operations further comprise subscribing to an event publishing service that publishes events comprising the event.
3. The system of claim 1 , wherein the type of the event is an editorial override event associated with the data item.
4. The system of claim 1 , wherein the type of the event is a news event that changes a broadcasting schedule associated with the data item.
5. The system of claim 1 , wherein the user interface menu is customized for the user.
6. The system of claim 1 , herein the user interface menu is associated with a video streaming service.
7. The system of claim 1 , wherein the first graph of user interface navigation elements comprises a watchlist.
8. A method comprising:
obtaining, by a system comprising a processor, a message associated with an event, where the message comprises a type of the event and a data item associated with the event; and
in response to determining that the event invalidates a first graph of user interface navigation elements pre-populated in a cache for anticipated future access, wherein the first graph of user interface navigation elements is associated with a user that interacts with a user interface comprising user interface navigation elements:
building, by the system, a second graph of user interface navigation elements corresponding to the event,
invalidating, by the system, the first graph in the cache, and
pre-populating, by the system, the cache with the second graph for the anticipated future access.
9. The method of claim 8 , further comprising subscribing, by the system, to an event publishing service that publishes events comprising the event.
10. The method of claim 8 , wherein the type of the event is an editorial override event associated with the data item.
11. The method of claim 8 , wherein the type of the event is a news event that changes a broadcasting schedule associated with the data item.
12. The method of claim 8 , wherein the user interface is customized for the user.
13. The method of claim 8 , wherein the user interface is associated with a media streaming service.
14. The method of claim 8 , wherein the second graph of user interface navigation elements comprises a watchlist.
15. A non-transitory machine-readable medium, comprising executable instructions, that when executed by a processor of a system, facilitate performance of operations, comprising:
receiving a notification associated with an event, where the notification comprises a type of the event and a data item associated with the event; and
in response to determining that the event invalidates a first graph of user interface navigation elements pre-populated in a cache for anticipated future access, wherein the first graph of user interface navigation elements is associated with a user that interacts with a watchlist comprising user interface navigation elements:
constructing a second graph of user interface navigation elements corresponding to the event,
invalidating the first graph in the cache, and
pre-populating the cache with the second graph for the anticipated future access.
16. The non-transitory machine-readable medium of claim 15 , further comprising subscribing to an event publishing service that publishes events comprising the event.
17. The non-transitory machine-readable medium of claim 15 , wherein the type of the event is an editorial override event associated with the data item.
18. The non-transitory machine-readable medium of claim 15 , wherein the type of the event is a news event that changes a broadcasting schedule associated with the data item.
19. The non-transitory machine-readable medium of claim 15 , wherein the watchlist is customized for the user.
20. The non-transitory machine-readable medium of claim 15 , wherein the watchlist is customized for the user.
