When you configure a synchronization task to write to an Amazon DynamoDB target, you can configure the target properties.
The target properties appear on the Target page of the Synchronization Task wizard when you specify an Amazon DynamoDB connection.
The following table describes the Amazon DynamoDB target properties:
Source Property
Description
Connection Type
Name of the target connection.
Target Object
Specify the target object for the task.
Create Target
Creates a target. Enter a name for the target object and select the source fields that you want to use. Default name is the source object name and by default, all source fields are used.
The target name can contain alphanumeric characters and the period and the underscore special characters. It cannot begin with a numeric character.
Note: You can create a target table only when the source table contains a single primary key.
You can also configure advanced target properties when you schedule the synchronization task.
The following table describes the Amazon DynamoDB advanced target properties:
Advanced Target Property
Description
Write Capacity Unit
The percentage increment of the write capacity unit. A unit of write capacity represents one write per second for items as large as 1 KB.
Note: When you create a table during the synchronization task, the default unit of write capacity is 1.
Success File Directory
Directory for the success file. Specify a directory path that is available on each Secure Agent machine in the runtime environment.
By default, Data Integration writes the success file to the following directory: <Secure Agent installation directory>/apps/Data_Integration_Server/data/success
Error File Directory
Directory for the error file. Specify a directory path that is available on each Secure Agent machine in the runtime environment.
By default, Data Integration writes the error file to the following directory: <Secure Agent installation directory>/apps/Data_Integration_Server/data/error
Write capacity unit
When you create or update a table, you can specify the provisioned throughput capacity using the write capacity unit for write operations. As your application data and access requirements change, you can increase or decrease your provisioned throughput by updating the write capacity unit.
A unit of write capacity represents one write per second for items as large as 1 KB. For example, if you specify 10 write capacity units, you are requesting a throughput of 10 writes per second of 1 KB size per second for that table.
To modify the write capacity unit, specify a percentage increment of the write capacity unit when you configure the advanced target properties. For example, if the existing write capacity unit is 100, you can write 1 KB of data per second to a table. To increase the number of writes by 20%, specify a value of 20 in the Write Capacity Unit field. You can now write 120 KB of data per second, which is 20% of existing unit of write capacity unit plus existing unit of write capacity.
