4 DynamoDB (Database)
| (require aws/dynamo) | package: aws |
DynamoDB is Amazon’s newer “NoSQL” service.
The intended use of this package is:
Set the dynamo-api-version parameter to a value such as "20120810".
Consult the DynamoDB documentation for the JSON format each operation uses.
Create an equivalent jsexpr?.
Call dynamo-request with the jsexpr? and the operation name (such as "CreateTable").
parameter
(dynamo-endpoint v) → void? v : endpoint?
= (endpoint "dynamodb.us-east-1.amazonaws.com" #f)
parameter
(dynamo-region) → string?
(dynamo-region v) → void? v : string?
= "us-east-1"
parameter
(dynamo-api-version v) → void? v : string?

procedure
(dynamo-request operation data) → jsexpr?
operation : string? data : jsexpr?
Consult the DynamoDB documentation for each operation. Supply the name of the operation as operation. Supply the jsexpr? equivalent of the documented JSON format as data.
