God IDynamoDBContext There are other methods that help with basic creation, reading, updating and deleting (CRUD) operations. Launch the app, and here it is! We have the API now retrieving the data from DynamoDB.

In the case below, I gave arn:aws:iam::aws:policy/AmazonDynamoDBFullAccess Which gives full access to DynamoDB resources. Add the appropriate permissions for DynamoDB. Set Access key and Secret key Navigate to the Identity and Access Management (IAM) In the console and under users, create a new user. God DynamoDBContext Requires only the AmazonDynamoDBClient.

The code above creates AmazonDynamoDBClient Use the credentials and area to access DynamoDB for your account. var client = new AmazonDynamoDBClient (credentials, config ) Var credentials = new BasicAWSCredentials ( '', '' ) var config = new AmazonDynamoDBConfig ( ) God Get The following method uses DynamoDBContext Perform the Query Action and get back all the items with the given city Name as partition key. The query operation allows you to select multiple items with the same partition / stack key and (if specified) apply filter conditions to the range / sort keys. Based on the city name (which is the hash / partition key), we can retrieve all the items in that partition.

Normally, we want to get the weather forecast for a city, so let’s update the Get method to get a city name. If you used Entity framework In the past, this context is very similar to the context of EF. Update WeatherForecastController Builder take the interface. God IDynamoDBContext Provides the methods needed to interact with DynamoDB. To get started, we’ll add the DynamoDB NuGet package. With the data set up in DynamoDB, let’s update the web API app to retrieve the data from DynamoDB. 'City' : 'Brisbane', 'Date' : 'T02:10:40.595Z', 'Summary' : 'Warm', 'TemperatureC' : 20īelow is a snapshot of the table with the number of items added to it.

We can add JSON data to the table as detailed below → on city and date properties, they contain a summary and temperature in Celsius in our queue WeatherForecast status. There can be any other asset on the item and it does not necessarily have to be the same for every item. To add items to a table from the portal, use Create an item button.īecause we specified the city and date as the combined master key, each item added to this table must have these two attributes. If we decide to store only part of the date, not including the time, then only one record per day. In this case, we can only accept one item for a city with a specific date and time. For the Sort key, we can use the Date property. For the master key, since the weather data is retrieved based on the city, we’ll make it the partition key. To store the WeatherFOrecast Let’s create a new table with the same name (you can use a different name if you want). The combination between them must be unique. Two items may have the same partition key However, they must have different sort keys. One attribute is the partition key, and the other is a sort key.

Partition key and sort key → A complex master key consisting of two features.

No two items can have the same partition key value

Partition key → Simple master key, with only one feature.

He asks you to enter the Table name and master key As shown below.ĭynamoDB supports two different types of master keys. To create a table, use the Create Table button on the DynamoDB page. The core components in DynamoDB are tables, Items and Characteristics.Ī table is a collection if items and each item is a collection of attributes. Make sure you are in the appropriate area where you want to create the table. To create a table that contains the weather data, refer to the AWS console And navigate to DynamoDB (by searching the top bar, Alt + S). Let’s add another property, City, goddess WeatherData Grade to identify the city of weather data. Let’s move this encoded data into DynamoDB and start retrieving it from there. It also comes with Swagger endpoint Prepare. It will create a default API application Weather Forecast A controller that returns some encoded data. If you use dotnet CLI, You can use dotnet new webapi Command to create a new web API application. To get started, let’s create the ASP NET Web API application from the default template.

We will learn how to create tables and perform basic Create Read, Update and Delete (CRUD) operations from the. In this post, let’s learn more about DynamoDB and its use from the.

DynamoDB is a fully managed database, which means you do not have to rotate server instances, software installations, or other maintenance tasks.
