This section provides examples of programming DynamoDB using the AWS SDK for Java. Example: @DynamoDbBean (converterProviders = { DefaultAttributeConverterProvider.class, MyCustomAttributeConverterProvider.class }); Share The following examples show how to use software.amazon.awssdk.services.dynamodb.model.QueryRequest.You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Click Enable NoSQL. Notice the custom fields (minus the one explained above), as explained below: @DynamoDBTable - Tells DynamoDBMapper that this model file corresponds to data stored in the table with the provided name @DynamoDBIndexHashKey - Indicates this attribute is to be used as the HashKey (sometimes also called PartitionKey) for our table. SDK v2 The default method to query the DynamoDB is to use asychronous calls, but you can use the promise () to use async, await method, so the request become synchronous.
