Retrieve Data From Dynamo DB Using Dynamo DB Connector In Mule

In This tutorial we will demonstrate how can we Retrieve Data From Dynamo DB Using Dynamo DB Connector In Mule 4.

Get Item : The GetItem operation returns a set of attributes for the item with the given primary key. If there is no matching item GetItem does not return any data and there will be no Item element in the response.

GetItem provides an eventually consistent read by default. If your application requires a strongly consistent read, set ConsistentRead to true. Although a strongly consistent read might take more time than an eventually consistent read, it always returns the last updated value
