Net::Amazon::DynamoDB::HighlyAvailable - Sync data across multiple regions

SYNOPSIS

use Net::Amazon::DynamoDB::HighlyAvailable;

# the regions param must have a length of 2
my $table = Amazon::DynamoDB::HighlyAvailable->new(
    table             => $table,       # required
    hash_key          => $hash_key,    # required
    range_key         => $range_key,
    regions           => [qw/us-east-1 us-west-1/],
    access_key_id     => ...,          # default: $ENV{AWS_ACCESS_KEY}
    secret_access_key => ...,          # default: $ENV{AWS_SECRET_KEY}
    timeout           => 1,            # default: 5
);

# create or update an item
$table->put(Item => { planet => 'Mars', ... });

# get the item with the specified primary key; returns a hashref
my $item = $table->get(planet => 'Mars');

# delete the item with the specified primary key
$table->delete(planet => 'Mars');

# scan the table for items; returns an arrayref of items
my $items_arrayref = $table->scan();

# scan the table for items; returns items as a hash of key value pairs
my $items_hashref = $table->scan_as_hashref();

# sync data between AWS regions using the 'last_updated' field to select
# the newest data.  This method will permanently delete any items marked as
# 'deleted'.
$table->sync_regions();

DESCRIPTION

Amazon says "All data items ... are automatically replicated across multiple Availability Zones in a Region to provide built-in high availability and data durability."

If thats not highly available enough for you, you can use this module to sync data between multiple regions.

This module is a wrapper around Net::Amazon::DynamoDB::Table.
