DDB

A Command Line tool for easily interacting with DynamoDB

Usage

Install:

go get -u github.com/patrobinson/ddb

Get the contents of an item where foo=bar. Quotes are optional for strings:

ddb -table test -command get -statement 'foo="bar"'

Create an Item with string and number types:

ddb -table books -command set -statement 'book="1984",author="George Orwell",isbn=9780143566496'

Bool types:

ddb -table books -command set -statement 'book="1984",bestseller=true'

String sets:

ddb -table authors -command set -statement 'author="George Orwell",books=("1984","Animal Farm")'

Number sets:

ddb -table authors -command set -statement 'author="George Orwell",isbns=(9780143566496,9780141036144,9780241341667)'

List:

ddb -table cricketers -command set -statement 'name="Sir Donald Bradman",testscores=[18,1,79,112,40,58,123,37]'

Map:

ddb -table cricketers -command set -statement 'country="Australia",players=`{"Tim Paine":{"Batting Avg": 34.78}}`'

Binary, loaded from a file:

ddb -table cricketers -command set -statement 'country="Australia",players={"players.gz"}'

Binary Set:

ddb -table cricketers -command set -statement 'country="Australia",players=({"players1.gz"},{"players2.gz"})'

Development Status

I consider this software to be "feature complete" so adding new features is unlikely, unless DynamoDB supports new data types. Bug reports and other inquiries though are welcome.

Supported Datatypes

• String
• Number
• Bool
• Number Set
• String Set
• List
• Map
• Binary Set
• Binary
