Thomas Mueller created OAK-201:
----------------------------------
Summary: NamespaceRegistry is very slow
Key: OAK-201
URL: https://issues.apache.org/jira/browse/OAK-201
Project: Jackrabbit Oak
Issue Type: Bug
Reporter: Thomas Mueller
The NamespaceRegistryImpl.getURI and getPrefix are called a lot, for example by
NamePathMapperImpl.getOakName.
The method doesn't do any caching, which is a problem because it has to read it
each time from the repository. Even if it would do caching, it wouldn't help
because it the method WorkspaceImpl.getNamespaceRegistry creates a new
NamespaceRegistryImpl each time it is called. To allow caching of known
mappings, the instance needs to be cached as well.
