Conditional commit for data in a database

1. A database, comprising:

a database interface, wherein the database interface enables a first transaction comprising a reading of a first set of information from the database at the same time as a second transaction comprising a second conditional write command of at least one element in the first set of information;

a database updater, wherein the database updater:

updates, using a processor, the first set of information according to a write command as part of the first transaction;

receives the second transaction comprising the second conditional write command for updating the at least one element in the first set of information in the database, wherein the second conditional write command includes one or more conditions based at least in part on a value of a database entry of the first set of information, wherein the one or more conditions limit changes allowable to the value of the database entry of the first set of information that occurred after the reading of the first set of information from the database, wherein the one or more conditions detect corruption of data and allow the database to execute read and write commands at full speed in order to reduce overhead associated with access locking;

updates the at least one element of the first set of information in the event that the one or more conditions in the second conditional write command is met; and

in the event that the one or more conditions in the second conditional write command is not met, abort the second transaction.

2. A database as in claim 1 , wherein the first set of information from the database comprises one or more data entries in the database.

3. A database as in claim 1 , wherein the database updater further receives a third transaction comprising a third conditional write command for a third set of information, wherein the third set of information comprises at least one element of the first set of information.

4. A database as in claim 1 , wherein one condition of the one or more conditions comprises a condition that a value of a database entry is less than an upper limit value.

5. A database as in claim 1 , wherein one condition of the one or more conditions comprises a condition that a value of a database entry is less than or equal to an upper limit value.

6. A database as in claim 1 , wherein one condition of the one or more conditions comprises a condition that a value of a database entry is more than a lower limit value.

7. A database as in claim 1 , wherein one condition of the one or more conditions comprises a condition that a value of a database entry is more than or equal to a lower limit value.

8. A database as in claim 1 , wherein one condition of the one or more conditions comprises a condition that a value of a database entry is equal to a predetermined value.

9. A database as in claim 1 , wherein the at least one element of the first set of information is updated to a first absolute value.

10. A database as in claim 1 , wherein the at least one element of the first set of information is updated to a value relative to a current value.

11. A database as in claim 10 , wherein the value relative to the current value is a value less than the current value.

12. A database as in claim 10 , wherein the value relative to the current value is a value greater than the current value.

13. A database as in claim 1 , wherein the reading of the first set of information from the database is read without a lock occurring during the read in the database.

14. A database as in claim 1 , wherein the reading of the first set of information from the database is read with a latch occurring during the read in the database.

15. A database as in claim 1 , wherein the reading of the first set of information from the database is read without a latch occurring during the read in the database.

16. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having been written since a specific prior read.

17. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having been written since a specific prior time.

18. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having not been written since a specific prior read.

19. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having not been written since a specific prior time.

20. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having been read since a specific prior read.

21. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having been read since a specific prior time.

22. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having not been read since a specific prior read.

23. A database as in claim 1 , wherein one condition of the one or more conditions comprises a value of a database entry having not been read since a specific prior time.

24. A method for a database, comprising:

enabling a first transaction comprising a reading of a first set of information from the database at the same time as a second transaction comprising a second conditional write command of at least one element in the first set of information;

updating the first set of information according to a write command as part of the first transaction;

receiving the second transaction comprising the second conditional write command for updating the at least one element in the first set of information in the database, wherein the second conditional write command includes one or more conditions based at least in part on a value of a database entry of the first set of information, wherein the one or more conditions limit changes allowable to the value of a database entry of the first set of information that occurred after the reading of the first set of information from the database, wherein the one or more conditions detect corruption of data and allow the database to execute read and write commands at full speed in order to reduce overhead associated with access locking;

updating the at least one element of the first set of information in the event that the one or more conditions in the second conditional write command is met; and

in the event that the one or more conditions in the second conditional write command is not met, abort the second transaction.

25. A computer program product for a database, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

enabling a first transaction comprising a reading of a first set of information from the database at the same time as a second transaction comprising a second conditional write command of at least one element in the first set of information;

updating the first set of information according to a write command as part of the first transaction;

receiving the second transaction comprising the second conditional write command for updating the at least one element in the first set of information in the database, wherein the second conditional write command includes one or more conditions based at least in part on a value of a database entry of the first set of information, wherein the one or more conditions limit changes allowable to the value of a database entry of the first set of information that occurred after the reading of the first set of information from the database, wherein the one or more conditions detect corruption of data and allow the database to execute read and write commands at full speed in order to reduce overhead associated with access locking;

updating the at least one element of the first set of information in the event that the one or more conditions in the second conditional write command is met; and

in the event that the one or more conditions in the second conditional write command is not met, abort the second transaction.
