Writing the sample JSON documents to DynamoDB

Configure tFixedFlowInput to load the sample data in the data flow and configure tDynamoDBOutput to write this data in a DynamoDB table.

About this task

Procedure

  1. Double-click tFixedFlowInput in its Component view.

    Example

  2. Click the ... button next to Edit schema to open the schema editor.

    Example

  3. Click the + button twice to add two rows, each representing a column of the sample data, and in the Column column, name these columns to DeliveryId and EventPayload, respectively.
  4. On the row for the DeliveryId column, select the check box in the Key column to use this DeliveryID column as the partition key column of the DynamoDB table to be used. A DynamoDB table requires a partition key column.
  5. Click OK to validate these changes and once prompted, accept the propagation of the schema to the connected component, tDynamoDBOutput.
  6. In the Mode area, select the Use Inline content radio box and enter the sample data in the field that is displayed:

    Example

    21058;{"accountId" : "900" , "accountName" :  "xxxxx" , "action" : "Create", "customerOrderNumber" : { "deliveryCode" :  "261" , "deliveryId" :  "313"}}
21059;{"accountId" : "901" , "accountName" :  "xxxxy" , "action" : "Delete", "customerOrderNumber" : { "deliveryCode" :  "262" , "deliveryId" :  "314"}}
  7. Double-click tDynamoDBOutput to open its Component view.

    Example

  8. Click the ... button next to Edit schema to open the schema editor. This component should have retrieved the schema from tFixedFlowInput.

    Example

  9. In the DB Type column, select JSON for the EventPayload column, as this is the column in which the JSON documents are stored.
  10. In the Access key and Secret key fields, enter the credentials of the AWS account to be used to access your DynamoDB database.
  11. From the Region drop-down list, select the AWS region to be used. If you do not know which region to select, ask the administrator of your AWS system for more information.
  12. From the Action on table drop-down list, select Drop table is exists and create.
  13. From the Action on data drop-down list, select Insert.
  14. In the Table name field, enter the name to be used for the DynamoDB table to be created.
  15. In the Partition Key field, enter the name of the column to be used to provide parition keys. In this example, it is DeliveryId.
