Abstract

Systems, methods, computer program product embodiments for deferred reading of email databases are described herein. An embodiment includes an event listener configured to poll (or query) the email server and selectively read an email database associated with the email server. Such a selective database read operation is based on the priority of an event occurring in the email server. If events of a low priority occur, the event listener does not open the email database immediately to retrieve additional information related to the low priority event but defers reading the email database by a pre-determined amount of time. If a higher priority event occurs, the email database is immediately read to retrieve details related to the high priority event from the mail server database. In another embodiment, event listener reads the email database based on when event timestamp information is updated by the email server.

Claims

1. A method for deferred reading of an email database, comprising:

(a) determining an occurrence of an event in an email server;

(b) determining priority of said event;

(c) reading said email database, when said event is of a first priority; and

(d) deferring reading of said email database by a pre-determined amount of time, when said event is of a second priority.

2. The method of claim 1, wherein step (a) comprises:

determining if a timestamp associated with said event has been updated by said email server.

3. The method of claim 1, wherein step (b) comprises:

checking if said event is an email arrival event.

4. The method of claim 1, wherein step (c) comprises:

reading email content and metadata associated with said email content.

5. The method of claim 1, wherein step (d) comprises:

deferring reading by a pre-determined amount of time measured from a last stored read time of said email database.

6. The method of claim 1, further comprising:

storing a time at which said email database is read.

7. The method of claim 1, further comprising:

transmitting said event to a synchronization server.

8. The method of claim 1, further comprising:

reading said second priority event to a synchronization server, when said pre-determined time has elapsed; and

reading said second priority event with said first priority event to said synchronization server, when said first priority event occurs prior to expiration of said pre-determined amount of time.

25. The method of claim 1, wherein said first priority is high priority, and said second priority is low priority.

9. A method for deferred reading of an email database, comprising:

determining if a timestamp has been updated by an email server;

reading said email database, when said timestamp has been updated by said email server; and

deferring reading of said email database by a pre-determined amount of time, when said timestamp has not been updated by said email server.

10. A system for deferred reading of an email database, comprising:

an email server; and

an event listener to determine an occurrence of an event in said email server,

wherein said event listener reads said email database, when said event is of a first priority and defers reading of said email database by a pre-determined amount of time, when said event is of a second priority.

11. The system of claim 10, wherein said email server is configured to generate a timestamp for said event.

12. The system of claim 10, wherein said email database comprises one or more mailboxes associated with one or more users.

13. The system of claim 10, further comprising a synchronization server.

14. The system of claim 13, wherein said synchronization server comprises one or more event queues.

15. The system of claim 14, wherein said synchronization server is configured to transmit said events in said event queue to a mobile device.

26. The system of claim 10, wherein said first priority is high priority, and said second priority is low priority.

16. (canceled)

17. A computer program product having control logic stored therein, said control logic enabling one or more processors to defer reading of an email database according to a method, the method comprising:

determining an occurrence of an event in an email server;

determining priority of said event;

reading said email database, when said event is of a first priority; and

deferring reading of said email database by a pre-determined amount of time, when said event is of a second priority.

27. The computer program product of claim 17, wherein said first priority is high priority, and said second priority is low priority.

18. A method for concurrent reading of events associated with an email database, comprising:

(a) determining if a timestamp has been updated by an email server;

(b) reading a first priority event from said email database, when said timestamp has been updated by said email server; and

(c) concurrently reading one or more second priority events, if any, with said first priority event during step (b).

19. The method of claim 18, further comprising providing data read in step (c) to a synchronization server.

20. The method of claim 18, wherein said first priority event includes arrival of an email in said email server.

21. The method of claim 18, wherein said second priority events include opening an email on a mobile device associated with said email server.

28. The method of claim 18, wherein said first priority is high priority, and said second priority is low priority.

22. A computer program product having control logic stored therein, said control logic enabling one or more processors to concurrently read events associated with an email database according to a method, the method comprising:

(a) determining if a timestamp has been updated by an email server;

(b) reading a first priority event from said email database, when said timestamp has been updated by said email server; and

(c) concurrently reading one or more second priority events, if any, with said first priority event during step (b).

23. A computer program product having control logic stored therein, said control logic enabling one or more processors to defer reading of an email database according to a method, the method comprising:

determining if a timestamp has been updated by an email server;

reading said email database, when said timestamp has been updated by said email server; and

deferring reading of said email database by a pre-determined amount of time, when said timestamp has not been updated by said email server.

24. A system for deferred reading of an email database, comprising:

an event listener to determine if a timestamp has been updated by an email server and read said email database; and

a deferring module to defer reading of said email database by a pre-determined amount of time.
