Setting up the Amazon DynamoDB Connector

Amazon DynamoDB Connector allows you to access the Amazon DynamoDB REST API from integration sequence.

Amazon DynamoDB makes it simple and cost-effective to store and retrieve any amount of data, as well as serve any level of request traffic. It uses a NoSQL database model, which is non-relational, allowing documents, graphs, and columnar among its data models.

Configuring message builders/formatters

Before you start configuring the Amazon DynamoDB connector, you also need to configure the integration runtime, and we refer to that location as <PRODUCT_HOME>.

Specific message builders/formatters configuration needs to be enabled in the product as shown below before starting the integration service.

If you are using the Micro Integrator of EI7 or APIM 4.0.0, you need to enable this property by adding the following to the /conf/deployment.toml file. You can further refer to the Working with Message Builders and Formatters and Product Configurations documentations.

[[custom_message_formatters]]
class="org.apache.synapse.commons.json.JsonStreamFormatter"
content_type = "application/x-amz-json-1.0"

[[custom_message_builders]]
class="org.apache.synapse.commons.json.JsonStreamBuilder"
content_type = "application/x-amz-json-1.0"

If you are using EI 6, you can enable this property by doing the following Axis2 configurations in the \repository\conf\axis2\axis2.xml file.

messageFormatters

<messageFormatter contentType="application/x-amz-json-1.0"
class="org.apache.synapse.commons.json.JsonStreamFormatter"/>

messageBuilders

<messageBuilder contentType="application/x-amz-json-1.0"
class="org.apache.synapse.commons.json.JsonStreamBuilder"/>

Note: If you want to perform blocking invocations, ensure that the above builder and formatter are added and enabled in the \repository\conf\axis2\axis2_blocking_client.xml file.
