Alex,
Maps and Sets are stored just like a regular Riak object, but using a particular data structure and object serialization format. As you have observed, there is an overhead, and you want to monitor the growth of these data structures. It is possible to write a MapReduce map function (in Erlang) which retrieves a provided object by type/bucket/id and returns the size of it's data. Would such a thing be of use? It would not be hard to write such a module, and I might even have some code for doing so if you are interested. There are also reasonably good examples in our documentation - http://docs.basho.com/riak/latest/dev/advanced/mapreduce I haven't looked at the Python PB API in a while, but I'm reasonably certain it supports the invocation of MapReduce jobs.
