Merging a Database
You can merge all of the forest data in the database using the Admin Interface. As described in Understanding and Controlling Database Merges, merging the forests in a database improves performance and is periodically done automatically in the background by MarkLogic Server. The Merge button allows you to explicitly merge the forest data for this database.
To explicitly merge the database, follow these steps:
Click Databases in the left tree menu. A list of databases appears.
Click your target database.
Click the name of the database you want to merge.
Click the Merge button.
A confirmation message appears.
Confirm that you want to merge the forest data in this database and click OK.
Merging data in a database is a “hot” admin task; the changes take effect immediately.
