Configuring Metadata Caching (Optional)

Configuring Metadata Caching (Optional)

The metadata caches manage items such as data objects, repository objects, and search tokens. The MDM Hub uses Infinispan for metadata caching. Infinispan is installed with the Hub Server. For the caches that are used by the Hub Server, the Infinispan configuration file contains default attribute values.
In version 10.1 and earlier, the MDM Hub used JBoss Cache for metadata caching. After you upgrade from one of these versions, the MDM Hub Server uses the Infinispan configuration file instead of the JBoss Cache configuration file.
If the JBoss Cache configuration file was edited in the previous version of MDM Hub, you might need to edit the Infinispan configuration file. It depends on why the file was edited.
Network policy
If the JBoss Cache file was edited to work around your organization's network policy, update the Infinispan file and the jgroups* file with the same policy changes.
Performance
If the JBoss Cache file was edited to improve cache performance, first try running the MDM Hub with the default Infinispan values. If you experience performance issues, copy the changed values from the JBoss Cache configuration file to the Infinispan configuration file. If you still experience performance issues, familiarize yourself with Infinispan and adjust the values to better suit your environment.
