    There isn't any way to do that.  The way that Lucene's indexes are 
    designed, obtaining that information is currently impossible, and it 
    would likely take a VERY large amount of development effort to make it 
    possible.  I would guess that even if it were possible, obtaining that 
    information would be very expensive in terms of system resources and time.

    The best you can do with current technology is estimate the size based 
    on document count compared to the whole index.  But if each tenant has 
    very different kinds of data in the index, that method would probably 
    give you inaccurate information.

    One thing you could do to have each one be its own collection is set up 
    multiple cloud installs, which can share one zookeeper ensemble by using 
    different chroot values for each one, and only put a few hundred 
    collections in each cloud.  This would probably require a lot of 
    additional hardware, and because of Lucene's economies of scale that 
    Walter was talking about, multiple collections WILL be larger on disk 
    than multiple tenants in one collection.

    Thanks,
    Shawn
