Provides a L<Future>-based API for Amazon's DynamoDB REST API.
See L<Amazon::DynamoDB::20120810> for available methods.

Current implementations for issuing the HTTP requests:

=over 4

=item * L<Amazon::DynamoDB::NaHTTP> - use L<Net::Async::HTTP>
for applications based on L<IO::Async> (this gives nonblocking behaviour)

=item * L<Amazon::DynamoDB::LWP> - use L<LWP::UserAgent> (will
block, timeouts are unlikely to work)

=item * L<Amazon::DynamoDB::MojoUA> - use L<Mojo::UserAgent>,
should be suitable for integration into a L<Mojolicious> application.  (not well tested)


=head1 NAME

Amazon::DynamoDB - support for the AWS DynamoDB API

=head1 METHODS

=head1 SEE ALSO

=over 4

=item * L<Net::Amazon::DynamoDB> - supports the older (2011) API with v2 signing, so it doesn't work with L<DynamoDB Local|>.

=item * L<AWS::CLIWrapper> - alternative approach using wrappers around AWS commandline tools

=item * L<WebService::Amazon::DynamoDB> - this module was based off of this initial code.



This module attempts to stick as close to Amazon's API as possible
while making some inconvenient limits easy to work with.

Parameters are named the same, return values are as described.
Documentation for each method is commonly found at:


For examples see the test cases, most functionality is well exercised
via tests.
