-- | The <tt>createDomain</tt> operation creates a new domain. The domain

createDomain :: AWSConnection -> DomainName -> IO ()

-- | The <tt>deleteDomain</tt> operation deletes a domain. Any items (and

--   complete.

listDomains :: AWSConnection -> IO [DomainName]

-- | Returns all of the attributes associated with the item. Optionally,
--   the attributes returned can be limited to one or more specified
--   attribute name parameters. If the item does not exist on the replica
--   that was accessed for this operation, an empty set is returned. The
--   system does not return an error as it cannot guarantee the item does
--   not exist on other replicas.
getAttributes :: AWSConnection -> DomainName -> ItemName -> [AttributeKey] -> IO Item

-- | The <tt>putAttributes</tt> operation creates or replaces attributes in
--   an item. Attributes are uniquely identified in an item by their
--   name/value combination. For example, a single item can have the
--   attributes <tt>["first_name" := "first_value"]</tt> and
--   <tt>["first_name" := "second_value"]</tt>. However, it cannot have two
--   attribute instances where both the name and value are the same. See
--   also <a>putAttributes'</a>.
putAttributes :: AWSConnection -> DomainName -> Item -> IO ()

-- | The <tt>putAttributes</tt> operation creates or replaces attributes in
--   an item. Attributes are uniquely identified in an item by their
--   name/value combination. For example, a single item can have the

--   <tt>["first_name" := "second_value"]</tt>. However, it cannot have two
--   attribute instances where both the name and value are the same.
--   
--   This command differs from <a>putAttributes</a> by taking a list of
--   attribute keys that are to be replaced instead of appended.

-- | With the <tt>batchPutAttributes</tt> operation, you can perform
--   multiple <tt>putAttribute</tt> operations in a single call. This helps
--   you yield savings in round trips and latencies, and enables Amazon
--   SimpleDB to optimize requests, which generally yields better
--   throughput.

deleteAttributes :: AWSConnection -> DomainName -> Item -> IO ()

-- | The <tt>select</tt> operation returns a set of Attributes for
--   ItemNames that match the select expression. <tt>select</tt> is similar
--   to the standard SQL SELECT statement. The total size of the response
--   cannot exceed 1 MB in total size. Amazon SimpleDB automatically
--   adjusts the number of items returned per page to enforce this limit.
--   For example, even if you ask to retrieve 2500 items, but each
--   individual item is 10 kB in size, the system returns 100 items and an
--   appropriate next token so you can get the next page of results.
