A Simple Example of Flyway Development using GitHub Branching

This article demonstrates one way to do branch-based database development with Flyway, using GitHub to manage the branches and Flyway configuration files to allow Flyway to switch smoothly between databases, when we move between branches in GitHub. Read more

A Version Control Strategy for Database DevOps

Our goal was to transform a 'serial' and manual development and release process into one that supported parallel development work and automated releases. This article explains step one: migrating our monolithic, centralized repos to Git, then implementing a Release Flow branching strategy for parallel development work streams, and a Pull Request workflow to control an automated build and release process.

Searching a Flyway Database

As a database gets larger, and development more complex, so it becomes increasingly necessary to be able to search for strings in the source files and the database itself. Maybe you need to find when a table first got created, when a foreign key was added, or to find out which tables lack documentation. I'll show you how to answer these sorts of questions by running simple 'wildcard' searches on your Flyway migration files, or source files, as well as more targeted searches on certain parts of your database model.

Cross-RDBMS Version Checks in Flyway

How does one check that a database is definitively at the version that Flyway says it is? Or that a test teardown procedure leaves no trace in the database? Or verify that an undo script returns a database's metadata to that state it should be in for the version to which you're rolling back? This article shows how to do high-level version checks, by comparing JSON models. Read more

Getting Started with Flyway CLI and any RDBMS

How to get started with Flyway, as simply as possible, using PowerShell. This article provides a practice set of Flyway migration scripts that will build the original pubs database on either SQL Server, PostgreSQL, MySQL, MariaDB or SQLite and then migrate it from version to version, making a series of improvements to its schema design.

Simple Reporting with Flyway and Database Models

If you can generate a file-based (JSON) model for each new version of a database, produced by a Flyway migration, then you have an easy way to run simple reports to help you search, list, and understand the structure of these databases. I'll show how to produce the models using PowerShell and then run some queries against them to generate the reports. Read more

Flyway and Simple Source Control

How to integrate Flyway database development with Source control, so that you can track what changes were made and who made them as well as which objects changed between versions, and how. Read more

Flyway How-tos: a User’s Perspective

Flyway provides a database-independent way for a team to track, manage and apply database changes, while maintaining strict control of database versions. It updates a database by running a series of versioned migration scripts, in order, and keeps track of all the changes in a special "schema history" table. It sounds simple, but it is easy to derail this team discipline if you don't find the right answers to the following questions… Read more

Database Development Visibility using Flyway and PowerShell

The payback of DevOps is not simply in automation but in using that automation to increase the visibility of the development processes. This article demonstrates way to make Flyway developments more visible, regardless of your RDBMS, such as by providing a detailed migration history, and change reports that reveal detail of what is going on to all involved. Read more

What is the Flyway Teamwork Framework?

The FlywayTeamwork PowerShell framework is designed to help get you started quickly with scripting Flyway migrations for a range of database systems. It introduces a PowerShell task library to help with the scripting of repetitive chores and to generate some of the 'build artifacts' that are often required during team development work. This article explains the basics of the framework's design and provides a demo how to use Flyway to migrate a PostgreSQL database, while generating a high-level narrative of the changes made between versions.
