Documentation
Definition
Activates the fast delta update of business object indexes for the Search Engine Service (SES).
Use
This function influences the way SES updates the TREX indexes, when business objects in the application are changed:
- If you do not set the flag SES writes change pointers and waits for the next delta update job to send the changed objects to the TREX index.
- If you set the flag the changed objects are immediately sent to the TREX index. The change pointers are also written as fall-back solution for example if TREX is temporarily not available.
The fast delta update reduces the latency of index updates. So you have more recent search results in SES.
Dependencies
To enable the fast update (with change pointers as fall-back) for a business object use the class CL_COM_SE_FAST_UPDATE.
To enable only the change pointer concept use the classCL_COM_SE_CPOINTER_UPDATE.
In case of mass changes of thousands of business objects at the same time we recommend to switch off the fast update for performance reasons.
