问题 We're testing the failover behaviour using the MariaDB JDBC connector Aurora specific features. We've set the JDBC URL as the documentation suggest: jdbc:mysql:aurora://cluster.cluster-xxxx.us-east-1.rds.amazonaws.com/db The problem is that as soon as we add the aurora: part in the URL schema, we can see an increase in the connections to the database writer until the point that we've to rollback the change (it even reaches 3.000 connections). Versions: MariaDB connector: 2.0.1 HikariCP

问题 I am looking a this Amazon page - https://aws.amazon.com/rds/aurora/serverless/ and it has this quote: You pay on a per-second basis for the database capacity you use when the database is active, and migrate between standard and serverless configurations with a few clicks in the AWS Management Console. I have a few normal Aurora clusters and want to switch them to serverless. I have looked and looked and cannot find the "migrate with a few clicks" bit in the Amazon user interface. I made a

问题 I have this query that updates some prices higher that 2 days ago, but does not work @Transactional @Modifying @Query("update HotelDailyPrice hdp set hdp.price = (select avg (hp.price) " + "from HotelPrice hp where hp.id = ?1 and hp.updateDate > CURRENT_DATE - 2), hdp.day = ?2 ") void updateDailyAveragePrice (Hotel hotel, String dayDate); 回答1: Actually, JPA doesn't support time periods operations because not all databases support it. So you have following options: Calculate date

问题 I am running an Amazon Web Services RDS Aurora 5.6 database cluster. There are a couple of lambda's talking to these database instances, all written in python. Now everything was running well, but then suddenly, since a couple of days ago, the python code sometimes starts throwing the following error: [ERROR] InterfaceError: 2003: Can't connect to MySQL server on 'CLUSTER-DOMAIN:3306' (-3 Temporary failure in name resolution) This happens in 1 every 1000 or so new connections.

问题 I've created a few Lambdas in AWS, and an Aurora RDS (publicly available). I couldn't execute lambdas (via call mysql.lambda_async ). When I tried that I got the error ERROR 1873: 1873: Lambda API returned error: Missing Credentials: Cannot instantiate Lambda Client . I tried attaching an IAM role called aurora-lambdas where I set full access to RDS and Lambdas and a trusted relationship between those services, but after trying various configurations I still get the issue. Do someone have
