Abstract

A method and apparatus for trigger-based cache population are disclosed. In the method and apparatus, a trigger for populating a session cache is detected and the session cache is populated with a plurality of aspects of data as a result of detecting the occurrence of the trigger. The plurality of aspects of the data are associated with a session established with a session service.

Claims

1. A computer-implemented method for trigger-based cache population, comprising:

receive, from a client device, a request for information associated with a session, the request including a session identifier, the session being purportedly established between the client device and a session service;

send an indication to the client device that the information associated with the session is not available for retrieval;

receive, from the client device, a request for session creation, one or more attributes of the client device being submitted in connection with the request for session creation; and

in response to the request, store, in a cache, a plurality of aspects of data for the session, an aspect of the plurality of aspects of the data being a data set and including at least a portion of the one or more attributes of the client device, the aspect of the plurality of aspects of the data being customized for and retrievable by a backend service of a plurality of backend services of the session service, wherein a first aspect of the plurality of aspects provided in response to a request for data by a first backend service of the plurality of backend services is different from a second aspect of the plurality of aspects provided in response to the same request for data by a second backend service of the plurality of backend services.

2. The computer-implemented method of claim 1, wherein the one or more attributes of the client device include hardware capabilities of the client device.

3. The computer-implemented method of claim 1, further comprising:

receiving updated client device attributes; and

updating the plurality of aspects of the data based at least in part on the updated client device attributes.

4. A system, comprising at least one computing device configured to implement one or more services, wherein the one or more services:

detect occurrence of a trigger, the trigger being receipt of a request for session establishment;

populate a cache with a plurality of aspects of data as a result of the occurrence of the trigger, an aspect of the plurality of aspects of the data customized for a corresponding backend service of a plurality of backend services of a session service, the plurality of aspects of the data pertaining to a session established with the session service, wherein a first aspect of the plurality of aspects provided in response to a request for data by a first backend service of the plurality of backend services is different from a second aspect of the plurality of aspects provided in response to the same request for data by a second backend service of the plurality of backend services; and

enable the backend service of the plurality of backend services of the session service to access the corresponding aspect of the plurality of aspects of the data.

5. The system of claim 4, wherein the request for session establishment is received from an intervening service in communication with a client device, the client device being party to the session established with the session service.

6. The system of claim 4, wherein the one or more services are further configured to receive a request for session information prior to receiving the request for session establishment.

7. The system of claim 6, wherein the one or more services are further configured to:

identify that the session information is not available for retrieval; and

send an indication that the session information is not available for retrieval.

8. The system of claim 7, wherein the indication is sent to a client device that is party to the session established with the session service or an intervening service in communication with the client device.

9. The system of claim 8, wherein the client device or the intervening service is configured to request the session establishment as a result of receiving the indication.

10. The system of claim 4, wherein the one or more services that are configured to populate the cache with the plurality of aspects of the data are further configured to populate the cache with one or more attributes of a client device that is party to the session established with the session service.

11. The system of claim 4, wherein the one or more services that are configured to enable the backend service of the plurality of backend services of the session service to access the corresponding aspect of the plurality of aspects of data are further configured to:

receive a request for data from the backend service; and

provide the aspect of the plurality of aspects corresponding to the backend service in response to the request.

12. A non-transitory computer-readable storage medium having stored thereon executable instructions that, as a result of execution by one or more processors of a computer system, cause the computer system to at least:

detect an occurrence of a trigger for populating a session cache;

populate the session cache with a plurality of aspects of data as a result of detecting the occurrence of the trigger, an aspect of the plurality of aspects of the data customized for a corresponding service of a plurality of services, the plurality of aspects of the data being associated with a session established with a session service, wherein a first aspect of the plurality of aspects provided in response to a request for data by a first service of the plurality of services is different from a second aspect of the plurality of aspects provided in response to the same request for data by a second service of the plurality of services; and

establish the session with the session service.

13. The non-transitory computer-readable storage medium of claim 12, wherein the instructions that cause the computer system to detect the occurrence of the trigger further include instructions that cause the computer system to receive a request for session creation from a client device that is a party to the session.

14. The non-transitory computer-readable storage medium of claim 12, wherein the instructions that cause the computer system to detect the occurrence of the trigger further include instructions that cause the computer system to receive a request for session creation from an intervening service in communication with a client device that is a party to the session.

15. The non-transitory computer-readable storage medium of claim 12, wherein the trigger is a change to one or more rules used to populate the session cache with the plurality of data aspects.

16. The non-transitory computer-readable storage medium of claim 12, wherein the trigger is based at least in part on a distribution of data received by the session service.

17. The non-transitory computer-readable storage medium of claim 12, wherein the plurality of services make the same application programming interface function call to retrieve, for each service, corresponding plurality of aspects of the data.

18. The non-transitory computer-readable storage medium of claim 12, wherein:

the instructions further comprise instructions that, when executed by the one or more processors, cause the computer system to receive a request for session data from the service of the plurality of services; and

the request for session data identifies the session and the service of the plurality of services.

19. The non-transitory computer-readable storage medium of claim 12, wherein the trigger is a session cache miss.
