Abstract

In an example embodiment, a system and method to store and retrieve application data from a cache and a database are provided. The example method may comprise receiving location data associated with application data from a user device, using the location data to determine a cache or database on which the application data is stored, and requesting application data from the cache or database. The system and method may further include monitoring requests for application data associated with instructions having a set of characteristics, identifying application data as associated with the instructions having the set of characteristics, and requesting the application data based on receiving subsequent instructions sharing the same set of characteristics.

Claims

1. A method comprising:

receiving location data from a user device, the location data comprising a cache identifier;

determining, using a processor, that a cache of a plurality of caches corresponds to the cache identifier; and

requesting application data from the cache based on the determination.

2. The method of claim 1, wherein the location data is received in a browser cookie.

3. The method of claim 1, wherein the cache identifier comprises a routing identifier, and wherein the determining that the cache of the plurality of caches corresponds to the cache identifier comprises:

querying a routing service with the routing identifier; and

receiving an identification of the cache.

4. The method of claim 1, wherein the location data comprises a database identifier, the method further comprising:

determining that the application data is not stored in the cache corresponding to the cache identifier; and

requesting the application data from a database of a plurality of databases based on the determination, the database corresponding to the database identifier.

5. The method of claim 1, further comprising:

modifying the application data; and

transmitting the modified application data to the cache corresponding to the cache identifier.

6. The method of claim 1, further comprising:

receiving new location data from a cache server hosting a cache, the new location data comprising a new cache identifier;

requesting application data from a second cache of the plurality of caches, the second cache corresponding to the new cache identifier; and

transmitting the new location data to a client browser in a cookie.

7. The method of claim 1, further comprising:

monitoring requests for application data associated with instructions having a set of characteristics;

compiling a list of application data associated with the instructions having the set of characteristics;

receiving subsequent instructions sharing the set of characteristics; and

requesting, based on the receiving of the subsequent instructions, the application data on the list.

8. The method of claim 1, wherein the application data comprises session data.

9. A system comprising:

a cache service module to receive location data from a user device, the location data comprising a cache identifier;

a data locator module to determine that a cache of a plurality of caches corresponds to the cache identifier; and

a data interface module to request application data from the cache.

10. The system of claim 9, wherein the cache service module receives the location data in a browser cookie.

11. The system of claim 9, wherein the cache identifier comprises a routing identifier, and wherein the data locator module is to:

query a routing service with the routing identifier; and

receive an identification of the cache.

12. The system of claim 9, wherein the location data comprises a database identifier and wherein:

the data locator module is to;

determine that the application data is not stored in the cache corresponding to the cache identifier, and

determine that a database of a plurality of databases corresponds to

the database identifier; and

the data interface module is to request the application data from the database corresponding to the database identifier.

13. The system of claim 9, wherein:

the cache service module is to determine that application data has been modified; and

the data interface module is to transmit the modified application data to the cache corresponding to the cache identifier.

14. The system of claim 9, wherein:

the data interface module is to;

receive new location data from a cache server hosting a cache, the new location data comprising a new cache identifier, and

request application data from a second cache of the plurality of caches, the second cache corresponding to the new cache identifier; and

wherein the cache service module is to transmit new location data to a client browser in a cookie.

15. The system of claim 9, further comprising:

a learning module to;

monitor requests for application data associated with instructions having a set of characteristics, and

compile a list of application data associated with instructions having the set of characteristics;

wherein the cache service module is to receive subsequent instructions, the subsequent instructions sharing the set of characteristics; and

the data interface module is to request, based on the receiving of the subsequent instructions, the application data on the list.

16. The system of claim 9, wherein the application data comprises session data.

17. A machine-readable medium comprising instructions, which, when executed by one or more processors, cause one or more machines to perform operations comprising:

receiving location data from a user device, the location data comprising a cache identifier;

determining that a cache of a plurality of caches corresponds to the cache identifier; and

requesting application data from the cache based on the determination.

18. A method comprising:

receiving instructions associated with application data;

assigning a cache to the application data;

generating location data comprising a cache identifier, the cache identifier corresponding to the cache; and

transmitting the location data to a user device.

19. The method of claim 18, further comprising:

transmitting the location data to a routing server.

20. A method comprising:

receiving instructions to perform an activity associated with application data;

receiving a browser cookie from a user device, the browser data comprising a routing identifier;

querying a routing service with the routing identifier;

receiving an identification of a cache; and

requesting the application data from the cache based on the identification of the cache.
