Overview

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

Examples:


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
}
