A BTree efficiently stores a large number of key,value pairs because the storage is split across a number of persistent objects (buckets) each of which stores a part of the tree, so only the bucket that changes needs to be stored when a key,value is updated.

Okay. So, if there are (say) 10 objects in a bucket. And, one of them changes. Then, are all 10 objects serialized again?
If they are not persistent objects themselves then yes. Laurence
