Hey Edward,
First, you should probably star issue 2740. Space used by indexes
is *not* included in your datastore statistics.
http://code.google.com/p/googleappengine/issues/detail?id=2740
Every property name is stored in every entity. So if you use long
descriptive property names you'll have lots of metadata. The property
names are also stored in your indexes, which can really multiply your
data! So the difference between your stored data on the quota page
and the size of all entities in the statistics, less your blobstore
and stored tasks, is probably pretty close to the size of your
indexes. If we could see stats on our indexes we'd know for sure
though, so star 2740.
You can reduce the space by explicitly disabling indexes on any
fields you're not querying or ordering by. You'll have to reput all
of your data to reclaim the space already used.
Also, don't forget, stored tasks also count against the stored data quota.
