问题 Scenario: I have two reader-aurora replicas. I make many calls to my system (high load) I see only one replica working at 99.30%, but the other one is not doing anything at all Why?, is because this second replica is ONLY to prevent failures of the first one?, cannot be possible to make both to share the load? 回答1: In your RDS console, you should be able to look at each of the 3 instances aurora-databasecluster-xxx.cluster-yyy.us-east-1.rds.amazonaws.com:3306 zz0.yyy.us-east-1.rds.amazonaws

问题 I am trying to provision an architecture with Terraform and ensure that applications have as little knowledge about anything going around them as possible. My goal is to have an app that uses Amazon's SDK to ask which RDS instances are available for it and then to connect to one of them. This way, no outside information( db-instance-identifier or Tag ) is required. The application would just describe the RDS instances, and since EC2 on which it runs would have been given permissions by

问题 I am trying to use AWS CLI to search for resources by tags. I prepare this tag.json file: { "TagFilters": [ { "Value": "postgres-dev", "Key": "Name" } ] } and use this command: aws resourcegroupstaggingapi get-resources --tag-filters --cli-input-json file://tag.json However, instead of returning only the databases which have this tag, it returns every resource in my AWS account (EC2, ELB, etc.) Can anyone show me where did I do wrong? Thanks a lot. 回答1: Can you try it in plain text syntax in

问题 I am doing a Python Lambda function to describe list of RDS snapshots created today. The challenge is how to convert the datetime.datetime.today() into a format which RDS client understands? UPDATE: I have implemented some changes suggested, I have added a string variable to convert the date expression into format which Boto3 RDS understands. 'SnapshotCreateTime': datetime(2015, 1, 1), today = (datetime.today()).date() rds_client = boto3.client('rds') snapshots = rds_client.describe_db

问题 I need to move millions of rows between identical mysql db's on two different rds instances. The approach I thought about is this: - use data-pipeline to export data from the first instance to amazon-s3 - use data-pipeline to import data from amazon-s3 to the second instance My problem is that I need to delete the data on the first instance at the end. Since we're talking about huge amounts of data I thought about creating a stored procedure to delete the rows in batches. Is there a way to

问题 I am able to connect normal AWS RDS MySQL instance (5.7.16). But, as I have to use MySQL as document store, I have configured MySQL instance by installing mysqlx plugin, Which is required for document store. After this, I am trying to connect MySQL document store on port 33060 on same instance but unable to connect. I am using lambda for connection which imports xdevapi (@mysql/xdevapi) package and tries to connect with MySQL RDS instance on port 33060. But, there is no error which I can see

问题 SOLVED: I was using USERNAME, not USER from previously attempting Postgres driver. I'm trying to connect my django project to an RDS MySQL database.

问题 Would like to inform upfront that I am new to AWS in general. For my project I am trying to use AWS RDS MySQL using IAM Authentication (IAM Role) from a Java application deployed on Tomcat on an EC2 instance. Before trying it from Java I am trying it from the command prompt on the EC2 instance.
