I am wondering if this problem may occur with Derby too?

yes, it does. derby's default blob size is 1M, iirc.


I would really like to better understand what may go wrong here. Please stop me at what point I am going wrong:

1/ The blob is used to persist a NodeState. A NodeState's heavy part is the 
ChildNodeEntries.

2/ ChildNodeEntries is mainly a double map of ChildNodeEntry

3/ a ChildNodeEntry is mainly NodeId.

4/ a NodeId is maily 2 long-s => 128bits

So, in order to meet the limitations of the DB schema, we should have a node that has as many children as a serialized LinkedMap, HashMap of ChildNodeEntry will fill the length of the field.

Is this the correct computation?
