This section describes how to set and manage a merge policy for
each Endeca data domain.
Using a merge policy for incremental updates
A merge policy determines how frequently the Dgraph merges incremental update generations in its index files, for a specific data domain.
Types of merge policies
You can set the merge policy to one of two settings: balanced or aggressive.
Setting or changing the merge policy
The mdex-config_MergePolicy attribute in the Global Configuration Record (or GCR) sets the merge policy for the Endeca data domain.
