Limitations
The operation for copying a Bamboo Book from the CI HUB to the local repository was quite chatty. Copying occurred recursively node by node in the hierarchy requiring a separate CMIS call for every node and data stream in the hierarchy. As a result, copy operations were painfully slow. One could easily imagine an optimization in which a copy request for objects of a predetermine type, e.g. Bamboo Book, could cause the repository to roll up the entire hierarchy into a single content package to be unpacked and its hierarchy reconstituted on the receiving side. Development ceased before optimizations of this sort could be undertaken.
