The Links table
Sitecore maintains a database table called Links
.The Links
table stores all links between individual items across databases (Core, Master, Web) and language versions.
Sitecore updates this table based on events that are triggered when actions on items (item:copied
, item:deleted
, item:saved
, item:versionRemoved
) are triggered.
There are two implementations of the database provider for this table:
-
SqlServerLinkDatabase (the default)
The default provider is configured in the
Sitecore.config
file. You can specify which database the links are saved in. The default is Core. The database name variable is defined in theSitecore/CMS.Core/Sitecore.Variables.config
configuration file. -
SqlServerBatchLinkDatabase
The main advantage of the SqlServerBatchLinkDatabase provider is storing new item links in
Links
table with help of batching. This improves performance considerably.
To use the SqlServerBatchLinkDatabase provider:
-
Enable the
App_Config/Include/Examples/SqlServerBatchLinkDatabase.config.example
file by removing the.example
from the file name.NoteWhen you enable the new provider, Sitecore removes all data from the
Links
table and the provider repopulates the table.
Rebuild the Links table
You may occasionally need to rebuild the Links
table, for example, as part of the upgrade process.
To rebuild the Links
table:
On the Sitecore Launchpad, open the Control Panel and in the Database section, click Rebuild link databases, select the Master and Core databases, and then click Rebuild.
