Delta indexes speed up updates of the master indexes. Index replication transfers changes made on master indexes to slave indexes.
Delta indexes and index replication are deactivated by default. The best time for activating them depends on which of the following scenarios you have:
Scenario | Procedure |
---|---|
Initial indexing of large data sets (more than 100,000 documents) |
|
No initial indexing of large data sets |

The sections below contain background information on delta indexes and index replication, and describe the configuration required.
