Description Daniel Pfeffer 2002-03-17 17:06:22 UTC 
MDR implements a storage layer to store all the data. As various simple 
operations in the NetBeans IDE can cause large amounts of data to be removed 
from the repository and large amounts of data to be added (e.g. by un-/mounting 
a filesystem), there is a need to be able to perform tasks like this an a 
reasonable time. In order to be able to achieve this performance, we decided to 
customize the storage layer to support storage federation. This mechanism 
should allow to split one logical storage into several physical storages 
(files). Mounting/unmounting these physical storages to/from a logical storage 
will cause fast addition/removal of the data.
Comment 1 Tomas Zezula 2002-06-12 13:32:03 UTC 
Implemented in Main Trunk.
The NBMDRepositoryImpl has been extended by method mountStorage,
umountStorage and createExtent with storageId. See Javadoc
documentation for more details.Also support for association links
crossing the extents were added.
