Global datastore and namespace index cause problems when migrating workspaces
-----------------------------------------------------------------------------
Key: JCR-1517
URL: https://issues.apache.org/jira/browse/JCR-1517
Project: Jackrabbit
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 1.4
Reporter: Tobias Bocanegra
Assignee: Tobias Bocanegra
Issue JCR-669 introduced a global namespace index. this is used by some
persistence managers in order to
keep the serialization of names small (fewer bytes).
unfortunately this forms a problem when a workspace needs to be migrated to
another repository with other namespace indexes. so an easy migration is not
possible unless you export/import the entire workspace using system view (which
is almost impossible for huge workspaces).
another potential problem is cause by the global data store, since all
workspaces share the same.
so when migrating a workspace, you would need to transfer all respective
records in the datastore to the target repository.
where the datastore problem can be solved by copying the respective items, the
namespace indexes are a bigger problem, since the serialized items need to be
adjusted.
suggest to alter the bundle pm to use the 'name index' for the namespaces as
well.
