Examples of com.amazonaws.services.dynamodb.model.PutItemRequest

com.amazonaws.services.dynamodb.model.PutItemRequest
Container for the parameters to the {@link com.amazonaws.services.dynamodb.AmazonDynamoDB#putItem(PutItemRequest) PutItem operation}.
Creates a new item, or replaces an old item with a new item (including all the attributes).

If an item already exists in the specified table with the same primary key, the new item completely replaces the existing item. You can perform a conditional put (insert a new item if one with the specified primary key doesn't exist), or replace an existing item if it has certain attribute values.
