Migrating Oracle databases to PostgreSQL on AWS, you often face challenges with converting system functions. Oracle has a rich set of built-in functions, and PostgreSQL doesn’t provide users with all of those. To support and simplify Oracle to PostgreSQL on AWS migrations, AWS Schema Conversion Tool provides users with an extension pack. After applying it to your Amazon Aurora PostgreSQL or Amazon RDS for PostgreSQL database, you may use the functions, which emulate the behavior of Oracle’s system functions. You […]

In my blog post Using Power BI to analyze Windows Perfmon data for SQL Server, I introduced a concept that I call “business-critical transactions” (BCT) to understand the overall throughput of your SQL Server applications. When I worked on the SQL Server team, the SQL Performance Engineering team used a set of customer applications with server-side replay scripts that would get executed before development teams checked in their code. If a development team’s build showed significant regression in performance, they could […]
In this second blog post for my series, Power BI for the SQL Server DBA, I’m going to show how you can take Windows Perfmon (Performance Monitor) data for SQL Server and analyze it with Power BI. You can find the source code, Power BI reports, and other related files on my GitHub site at https://github.com/db-best-technologies/power-bi-for-sql-dbas. Here is a summary of what’s coming up in the series. It is subject to change based on feedback and reader demand: Capturing performance […]
Over the last few months of benchmarking SQL Server performance on AWS, I discovered a way to optimize SQL Server performance running on EC2 instances by paying close attention to several key Windows performance counters. This blog post is the first in my new series called Power BI for the SQL Server DBA. I’m going to show how you can easily capture performance counters to optimize SQL Server performance and cost on AWS EC2 instances. I’m going to start with […]
Last year, we published the blog post on Validating AWS EC2 SQL Server Deployments Using Benchmark Tools. Since then, AWS released enhancements like Optimizing CPU Option that allow you to choose a larger EC2 instance for your SQL Server 2017 instances for greater Memory and IOPS / vCPU to keep your licensed vCPU count down.
Read this bog post to discover how benchmarking your SQL Server workloads on AWS in a pre-production environment can help you pick the best candidate EC2 instance with an optimized storage configuration based on real data.

Looking for greater flexibility, speed, and scale for your Apache Cassandra solutions? It’s time to consider Amazon’s DynamoDB as a great alternative. We would like to share our hands-on experience and insights for those looking to migrate Apache Cassandra to Amazon DynamoDB using the new data extraction agents that AWS recently released with the Schema Conversion Tool. This migration approach involves adding an additional datacenter to an existing Cassandra cluster. This datacenter clones all data from the original cluster, and […]
