Abstract
A system and method for implementing distributed transactions using configuration data that is available to all applications which may wish to access the data. Added to the configuration data is at least one status indicator to allow applications to ascertain the status of updates without performing a database-specific distributed transaction. An application which is preparing to write/update stored information must first change the at least one status indicator associated with the underlying storage. Thereafter, any other application which has a need to read or write the stored information will readily ascertain the status of the stored information from the configuration data. The other application which has need of the data may choose to read the old and/or partially updated data or may wait until the update has been completed and the at least one status indicator has been changed to indicate completion of the update. Status indicators may be associated to entire nodes at which data is stored or to specific pieces (e.g., keys) of the stored data. Furthermore, the status indicator of the configuration data can be displayed to a user.
