Writing and extracting JSON documents from DynamoDB
Use tDynamoDBOutput to write a JSON document to a DynamoDB table and then use tDynamoDBInput to extract a child element of this JSON element.
Prerequisites:
- A Talend Studio with Big Data
- Your AWS credentials that have been granted the access to your Amazon DynamoDB.
The sample data to be used reads like
this:
21058;{"accountId" : "900" , "accountName" : "xxxxx" , "action" : "Create", "customerOrderNumber" : { "deliveryCode" : "261" , "deliveryId" : "313"}}
21059;{"accountId" : "901" , "accountName" : "xxxxy" , "action" : "Delete", "customerOrderNumber" : { "deliveryCode" : "262" , "deliveryId" : "314"}}
This data has two columns: DeliverID and EventPayLoad, seperated by a semicolon (;). The JSON document itself is stored in the EventPayLoad column.
