A cache update policy provides a variety of options by which data refresh is controlled for a given create, update, or delete operation, ranging from applying only the results to the cache to invalidating the MBO and refreshing all data (invalidate the cache).
Typically, any EIS data-changing operation invalidates the MBO data to which it is bound, requiring it to be refreshed. This can be inefficient and unnecessary, depending on the nature of the data that changes.
- The device application initiates a create, update, or delete operation.
- Unwired Server passes the operation to the EIS, where the operation is executed.
- The CDB is updated based on the cache update policy. A subsequent synchronization reflects the changed CDB.
