Proxy cache aggregator
View Patent ↗A social data aggregator generates entries of action data describing actions taken by users of a social networking system. The entries are archived in a number of remote data hosts, with a portion of the entries stored in an action cache to expedite retrieval. The action cache is modified to include relevant entries of action data by selecting the most relevant entries from proxy data aggregators, which identify sets of entries from remote data hosts coupled to the proxy data aggregators based on the relevance of the entries in the remote data hosts. The relevance of an entry is based on an associated engagement score indicating a likelihood of a user requesting content interacting with a notification based on an entry.
1. A method comprising:
storing, in a plurality of remote data hosts, entries of action data describing actions performed by one or more users of a social networking system, each remote data host storing a subset of entries of the action data;
receiving a triggering event to modify an action cache;
determining an engagement score for each of the entries of action data, the engagement score of an entry indicating a probability of a user interacting with a notification based on the entry;
determining a plurality of proxy sets associated with a plurality of proxy data aggregators, a proxy set including entries of action data, each proxy set determined from engagement scores of entries of action data stored in one or more remote data hosts coupled to a proxy data aggregator;
receiving the plurality of proxy sets at a social data aggregator;
selecting entries of action data from the plurality of proxy sets based on the engagement scores associated with the entries of action data; and
storing the selected entries of action data in the action cache.
2. The method of claim 1 , wherein the engagement score for an entry of action data is based at least in part on prior interactions with a notification based on the entry by users of the social networking system.
3. The method of claim 1 , wherein the engagement score for an entry of action data is based at least in part on an affinity between a user requesting a notification and an object associated with the entry of action data.
4. The method of claim 1 , wherein determining the engagement score for each of the entries of action data comprises:
capturing interactions with a notification based on a entry by one or more users of the social networking system; and
modifying an engagement score of an entry based on the captured interactions.
5. The method of claim 1 , wherein the engagement scores are determined responsive to receiving the information about the triggering event.
6. The method of claim 1 , wherein the trigger event comprises receiving a request from a client device for notification data.
7. The method of claim 1 , wherein the trigger event comprises receiving action data from a client device.
8. The method of claim 1 , wherein the trigger event comprises a signal generated at a defined time interval.
9. A method comprising:
storing, in a plurality of remote data hosts, entries of action data each describing actions performed by one or more users of a social networking system, each remote data host storing a subset of the action data;
receiving a triggering event to modify an action cache;
determining an engagement score for each of the entries of action data, the engagement score of an entry indicating a probability of a user interacting with a notification based on the entry;
determining a plurality of proxy sets associated with a plurality of proxy data aggregators, a proxy set including entries of action data, each proxy set determined from engagement scores of entries of action data stored in one or more remote data hosts coupled to a proxy data aggregator;
receiving a plurality of proxy sets at a social data aggregator;
applying one or more rules to the entries stored in each of the plurality of proxy sets to identify one or more candidate entries of action data;
selecting one or more entries of action data from the candidate entries of action data based at least in part on the engagement scores; and
storing the selected one or more entries of action data in the action cache.
10. The method of claim 9 , wherein applying one or more rules to the entries stored in each of the plurality of proxy sets to identify one or more candidate entries of action data comprises:
prioritizing entries stored in at least one proxy set based on application of the one or more rules; and
identifying the one or more candidate entries based at least in part on the prioritization.
11. The method of claim 9 , wherein the engagement score for an entry of action data is based at least in part on prior interactions with a notification based on the entry by users of the social networking system.
12. The method of claim 9 , wherein the engagement score for an entry of action data is based at least in part on an affinity between a user requesting a notification and an object associated with the entry of action data.
13. The method of claim 9 , wherein determining the engagement score for each of the entries of action data comprises:
capturing interactions with a notification based on a entry by one or more users of the social networking system; and
modifying an engagement score of an entry based on the captured interactions.
14. The method of claim 9 , wherein the engagement scores are determined responsive to receiving the information about the triggering event.
15. The method of claim 9 , wherein the trigger event comprises receiving a request from a client device for notification data.
16. The method of claim 9 , wherein the trigger event comprises receiving action data from a client device.
17. The method of claim 9 , wherein the trigger event comprises a signal generated at a defined time interval.
18. A method comprising:
storing, in a plurality of remote data hosts, entries of action data each describing actions performed by one or more users of a social networking system, each remote data host storing a subset of the action data;
receiving a triggering event to modify an action cache;
determining an engagement score for each of the entries of action data, the engagement score of an entry indicating a probability of a user interacting with a notification based on the entry;
determining a plurality of proxy sets associated with a plurality of proxy data aggregators, a proxy set including entries of action data selected based on engagement scores of entries of action data stored in one or more remote data hosts coupled to a proxy data aggregator and application of one or more rules to entries of action data stored in the one or more remote data hosts coupled to the proxy data aggregator;
receiving the plurality of proxy sets at a social data aggregator;
selecting entries of action data from the plurality of proxy sets based on the engagement scores associated with the entries of action data; and
storing the selected entries of action data in the action cache.
