Parent: Object

SimpleDB can report on the amount of data stored in a domain, the number of items, etc.

@example 

 sdb = SimpleDB.new
 sdb.domains['mydomain'].metadata.to_h

 # the hash returned above might look like:
 {
   :timestamp => 1300841880,
   :attribute_names_size_bytes => 12,
   :item_count => 1,
   :attribute_value_count => 6,
   :attribute_values_size_bytes => 25,
   :item_names_size_bytes => 3,
   :attribute_name_count => 3
 }
