The Pervasive Nature of Open Source

Or you might think that because you use OSS software, most of the world also does. Microsoft, Oracle, […]

Planning a Database Testing Strategy for Flyway

  • Article

With Flyway, you can adopt a test-driven development strategy that will allow you to test and evaluate databases, and database objects, at every phase of the database development lifecycle. The further down the delivery pipeline that bugs appear, the more costly in time and resources they are to fix. This approach will allow you to catch many of them before the database change even gets committed to version control, making a continuous delivery process much easier to adopt and sustain.

How We Ate Our ​Own Dog Food​ To Level-Up Internal Testing with Redgate Clone

  • Article

Most applications have large and complex databases at the back end, making it hard for developers to adequately test their work before it goes out. Having a fast, repeatable process to deliver data on demand is an essential part of an effective software development lifecycle, ultimately leading to improved customer satisfaction. In this article, we’ll explore the journey our own engineering team went on to leverage our own tool, Redgate Clone, to spin up short-lived database instances in containers for automated testing.

Stairway to SQL Server Automated Database Testing

  • Stairway

Automated testing is a way to ensure you can repeatedly examine your code as you make changes by running a series of tests. Since these are automated, you have the ability to execute all tests with one programmatic call rather than hoping a developer runs all tests. This also allows the effort of writing tests […]

Question of the Day

SQL Server Columnstore Index Fragmentation

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?
