Hello Eric, thank you for your update. In fact I was suspecting the index or other management data. But it is hard to believe that it leads to such a big overhead. I mean it is enormous to have an index that is 10 times more than the actual data, don't you think so? Furthermore in the datastore statistics they already list so called "Metadata". It is consuming about 44% of the space. I think that this is the index, is it not? Maybe you are right an we got to wait. The statistics are already a great new feature to better understand things.
