Amazon‌ ‌RDS‌ ‌Proxy:‌ ‌Taming‌ ‌DB‌ ‌Connections

Most developers find databases difficult to scale. There are a lot of frameworks that can run on multiple pods⁠—or even multiple clusters⁠—to handle more load. Some frameworks even support advanced load balancing and caching.

Still, when a spike beyond what the framework can handle happens, the database is almost always the first process to fail. It’s a horror story that every developer has experienced at least once. And it always happens at the most important moment⁠—such as during an important flash sale.

Taming database load management isn’t an easy task, but Amazon Relational Database Service (RDS) has been doing a great job at it. Amazon RDS Proxy though extends the features you can use to manage database connections to a whole new level.

Usecase with RDS Snapshot Export to S3

AWS recently announced “Amazon RDS Snapshot Export to S3” feature wherein you can now export Amazon Relational Database Service (Amazon RDS) or Amazon Aurora snapshots to Amazon S3 as Apache Parquet, an efficient open columnar storage format for analytics.

I had a use-case to refresh Athena tables daily with full data set in Account B(us-east-1) from Aurora MySQL database running under Private subnet in Account A (us-west-2). The two solutions I could think of was -

  1. Have EC2 instance running in Public subnet to act as bridge to the Aurora instance and configure SSH Tunnel to pull the data to S3 using python script.
  2. Use the newly released RDS snapshot export to S3 feature creating a server-less solution.

I used this new feature with cross-region replication enabled for S3 bucket to replicate the data to S3 bucket in Account B.

In this post, I will go through the steps to have the data into staging bucket of Account B and few issues I faced during this setup -

1. Setup Cross-Region replication between the Source S3 bucket in Account A(us-west-2) and Destination Bucket in Account B(us-east-1).

I created a new S3 Bucket and navigated to Replication under Management tab. For both the source and destination S3 buckets versioning needs to be enabled. If you want to replicate objects encrypted with AWS KMS make sure to enable the check box under Replication criteria.

Spring Boot: Handle AWS RDS Password Change or Rotation Without Restarting

This article is about how you can handle AWS RDS secrets rotation without restarting your Spring Boot application.

This article is about how you can handle AWS RDS secrets rotation without restarting your Spring Boot application.

I had this problem wherein I had to update my database connection whenever the database password was updated for my AWS RDS instance. This can be because of a monthly password rotation policy or maybe the database credentials got compromised and you want all your running applications to keep running even when the database password is changed.

To solve this kind of problem, AWS provides a library that will handle this updating of the database connection without even restarting your Spring Boot application.

AWS has an open-source library called AWS Secrets Manager JDBC, that handles database connections while your application is running and talking to the RDS instance.

Let’s see how this works.

Capturing deadlocks on AWS RDS SQL Server databases

This article will explore the process to capture deadlock XML and deadlock graphs for AWS RDS SQL Server databases.

Introduction

As a database professional, you confront the performance issues with databases. It might be due to a lack of indexes, improper indexes, poorly written T-SQL statements, outdated statistics, blocking, or deadlocks. It is essential to monitor the deadlocks in a SQL database irrespective of hosting on-premises or Cloud infrastructure.

Usually, we receive the following error in an application if SQL Server kills a process as the deadlock victim.
