return new AmazonDynamoDBClient(clientConfig) - Return the AmazonDynamoDBClient using the configuration.Īfter registering IAmazonDynamoDB in our application, we are now in the position to insert it using Microsoft Dependency injection in the our Controller. var clientConfig = new AmazonDynamoDBConfig - Create an AmazonDynamoDBConfig instance passing in the LocalServiceURL from appsetting.json. services.AddSingleton - Register a service IAmazonDynamoDB interface which returns the actual implementation. 
Due to the API limitations of CloudWatch, there can be a delay of as many as 20 minutes before our system can detect these issues. Avoid using scan operations like the plague which scan the entire database contents. Choosing the Right DynamoDB Partition Key (Amazon) Amazon DynamoDB Accelerator (Amazon) Note: Our system uses DynamoDB metrics in Amazon CloudWatch to detect possible issues with DynamoDB. Especially when you are retrieving large item collections. DynamoDB is designed for single-digit millisecond latency, but some workloads will experience higher latency than that. It does not reflect network or client latency, or latency of non-successful requests.
You will sometimes be surprised at the results your queries are returning. Latency refers to the amount of time successful requests take in the DynamoDB system.
var runLocalDynamoDb = dynamoDbConfig.GetValue("LocalMode") - Gets the value of local mode Test and debug apps locally first with a local DynamoDB and single-step in a debugger to check your queries. var dynamoDbConfig = Configuration.GetSection("DynamoDb") - Gets the section DynamoDb from the configuration file. For this, you have to enter the following command. After this, the next step is to check tables on the local server. It uses the label global due to the capability of queries/scans on the index to span all table data, and over all partitions. As soon as you enter this command, you’ll see the list of all the tables available on the live server. Return new AmazonDynamoDBClient(clientConfig) DynamoDB offers two types of secondary indexes Global Secondary Index This index includes a partition key and sort key, which may differ from the source table. ServiceURL = dynamoDbConfig.GetValue("LocalServiceUrl") Var clientConfig = new AmazonDynamoDBConfig Var runLocalDynamoDb = dynamoDbConfig.GetValue("LocalMode") #Check local dynamodb code#
Copy Code var dynamoDbConfig = Configuration.GetSection("DynamoDb")
