Article Overview In this article we will learn how to integrate a Spring boot application with Apache Cassandra database and Redis cache. This is an extension to one of our previous articles which demonstrates the steps to set up Apache Cassandra and how to integrate is with Springboot, link shared below. https://www.sqlservercentral.com/articles/cassandra-springboot-integration In this tutorial […]
One of my favorite things about going to in-person events is just the time when we're sitting around chatting, out in the hallway, over at the vendor booths, maybe in the speaker room. Any of them. Inevitably, you start to get what I would call "sea stories" (Navy & Coasties, "war stories" for the pickles, […]
This article shows the final step of an availability group creation, specifically for a distributed clusterless one.
Working across Oracle, SQL Server, PostgreSQL, and MySQL, I've learned that the real challenge isn’t just knowing each platform, but understanding the subtle differences in terminology, syntax, and mindset, and staying open to learning on the fly every time I jump in. The “Sacred Six” are rules that I’ve learned to live by and accept. […]
If you’ve ever had to format dates and times in SQL, you’ve probably come across one of the most jarring realities of working across platforms: every major RDBMS does it differently and sometimes confusingly. What’s a TO_CHAR() in Oracle becomes FORMAT() or CONVERT() in SQL Server, and its sort of the same in PostgreSQL… but […]
With the ever-increasing pace of the digital era, companies are continuously looking for opportunities to enhance efficiency, cut costs, and optimize operations. The most viable way to accomplish these is through Custom Automation Software Development.
This is a list of the builds for SQL Server 2022. There are other build lists available here. A list of all the builds that I can find and install on my Build VM. If you find a build not listed here, please let the webmaster know (webmaster at sqlservercentral.com). All builds are listed in reverse […]
Get a quick glimpse of using AI in SQL Server by implementing a machine learning system.
This article explores how to securely clone the master user permissions in Amazon RDS for SQL Server using a custom stored procedure, usp_rds_clone_login. It outlines a step-by-step process to generate, review, and apply a script that replicates server- and database-level access from the master user to a new login without directly exposing elevated credentials. The guide emphasizes the principle of least privilege, supports named account management, and enables transparent, auditable permission handling for DBAs and applications. Designed for secure and scalable environments, this solution enhances operational security while maintaining administrative flexibility in Amazon RDS.

Comments posted to this topic are about the item SQL Server Columnstore Index Fragmentation
Hi i was surprised to see the approach my coworkers used to sunset talend...
The columnstore index is absolutely different than the traditional rowstore b-tree index. Because of this, it doesn't suffer from the same kind of fragmentation across pages as the b-tree index. Yet, it does suffer from a type of fragmentation brought about by an excess of deleted rows in a rowgroup and a lack of compression of storage because more things are in the delta store. While b-tree indexes use dm_db_index_physical_stats to show fragmentation, which system tables or DMVs can be used in SQL Server (prior to SQL Server 2025) to determine columnstore fragmentation?
