Simple perl interface for Amazon DynamoDB

NAME

Net::Amazon::DynamoDB - Simple interface for Amazon DynamoDB

DESCRIPTION

Simple to use interface for Amazon DynamoDB

If you want an ORM-like interface with real objects to work with, this is implementation is not for you. If you just want to access DynamoDB in a simple/quick manner - you are welcome.

See https://github.com/ukautz/Net-Amazon-DynamoDB for latest release.

SYNOPSIS

my $ddb = Net::Amazon::DynamoDB->new(
    access_key => $my_access_key,
    secret_key => $my_secret_key,
    tables     => {
        
        # table with only hash key
        sometable => {
            hash_key   => 'id',
            attributes => {
                id   => 'N',
                name => 'S'
            }
        },
        
        # table with hash and reange key key
        othertable => {
            hash_key   => 'id',
            range_key  => 'range_id',
            attributes => {
                id       => 'N',
                range_id => 'N',
                attrib1  => 'S',
                attrib2  => 'S'
            }
        }
    }
);

# create both tables with 10 read and 5 write unites
$ddb->exists_table( $_ ) || $ddb->create_table( $_, 10, 5 )
    for qw/ sometable othertable /;

# insert something into tables
$ddb->put_item( sometable => {
    id   => 5,
    name => 'bla'
} ) or die $ddb->error;
$ddb->put_item( sometable => {
    id        => 5,
    range_key => 7,
    attrib1   => 'It is now '. localtime(),
    attrib1   => 'Or in unix timstamp '. time(),
} ) or die $ddb->error;

credentials returning as undef in return sub

Can't use an undefined value as a HASH reference at /usr/lib/perl5/site_perl/5.14.2/Net/Amazon/DynamoDB.pm line 1544.

$self->_credentials->{ SecretAccessKey }

is returning as undef ...

N for range search

Hello.

is there any reason that you have

$value = $item_ref->{ $key } .'';

in line 720. the . '' seems quite weird for me when the key is N.

for example, I set table as

{"Table":{"CreationDateTime":1.350285647082E9,"ItemCount":0,"KeySchema":{"HashKeyElement":{"AttributeName":"id","AttributeType":"S"},"RangeKeyElement":{"AttributeName":"version","AttributeType":"N"}},"ProvisionedThroughput":{"ReadCapacityUnits":10,"WriteCapacityUnits":5},"TableName":"test_picture","TableSizeBytes":0,"TableStatus":"ACTIVE"}}

then put_item I set

{"Item":{"keywords":{"S":"Perl\nDynamoDB"},"filename":{"S":"1.jpg"},"date":{"N":"1350287320"},"version":{"N":"1"},"id":{"S":"MPCBvJwW4hGSd_kERh+kNg"},"tbuser":{"N":"999"}},"TableName":"test_picture"}

see, you have version converted into "1" here. actually I set version=1 in Perl.

and it will be broken for

get_item('test_picture', { id => $id, version => 1})

{"TableName":"test_picture","ConsistentRead":false,"Key":{"RangeKeyElement":{"N":1},"HashKeyElement":{"S":"MPCBvJwW4hGSd_kERh+kNg"}}}

it returns error
'_content' => '{"__type":"com.amazon.coral.service#SerializationException","Message":"class java.lang.Short can not be converted to an String"}',

but if I query with

get_item('test_picture', { id => $id, version => "1"})

it works:

{"TableName":"test_picture","ConsistentRead":false,"Key":{"RangeKeyElement":{"N":"1"},"HashKeyElement":{"S":"BO+oGaAW4hGmv4ycE82ppw"}}}

I just do not understand why we have . ''; when put_item?

any idea?

Thanks

Token Key Expired

i got a small bug, while i connected my site to DynamoDB , token is key is expired after the token time is out .. but programme is grabs the token id into ram.Getting the same error after every time after the token expired

Token is alive for one hour, it would be resource consuming to get token for every request.

i got a small request that if u could get the implement that in the request token after it expired which can be done at
line 1595 #handle errror in module
i could have pulled through GIT but not to able to find the error API of the STS
That would be a better option , atleast could u pass the code for me
Thank You

how about to move from Moose to Moo?

does it looks sane?

if you're interested, I'll be very glad to do that.

Thanks

Use something other than Cache

This is a pretty old module that requires DB_File which requires Berkeley DB 1.x. I can't get that to compile in some places.

Parameter for _security_token_url ?

Hi,

Is possible pass _security_token_url as parameter or some another way ?

Today is fixed:

has _security_token_url => ( isa => 'Str', is => 'rw', default => 'https://sts.amazonaws.com/?Action=GetSessionToken&Version=2011-06-15' );

But when you create on endpoint (for private VPCs) we need use : "sts.us-east-1.amazonaws.com" not "sts.amazonaws.com"

I copy module and replace that and works fine with :

has _security_token_url => ( isa => 'Str', is => 'rw', default => 'https://sts.us-east-1.amazonaws.com/?Action=GetSessionToken&Version=2011-06-15' );

Best Regards
