This article discusses Flyway's transition from CONF to TOML configuration files. It highlights the advantages of TOML, such as improved readability, flexibility in managing complex database configurations, and support for specifying multiple database environments. It also discusses a few of the differences to be aware of when switching existing Flyway…Read more
If you're using a Linux-based operating system, Bash is the obvious choice of scripting language for Flyway. This article demos the basics of dealing with credentials in team-based database development, when using 'traditional' flyway.conf files, and how to save and parse the JSON output of Flyway commands, for example to…Read more
Redgate Monitor now offers improved security for monitoring PostgreSQL on Amazon RDS and Aurora DB clusters, as well as for retrieving enhanced metrics from any RDS instance.Read more
The Validate command aims to ensure that Flyway can reliably reproduce an existing version of a database from the source migration scripts by warning you if files are retrospectively added, removed or altered that would prevent it from doing so. Validation errors are Flyway's warning that "the source for this…Read more
The Clean command resets a database to its initial state, before any Flyway migrations were applied. In other words, it empties the database. This can be useful for any development task that requires that you recreate the database structure, or for tearing down a test harness. It also allows you…Read more
A Flyway Baseline migration script is a single script with a B prefix that will migrate an empty database, or one that Flyway has 'cleaned', to the version specified in the file name. It is useful both for consolidating a long, often complex chain of historical migrations, and for capturing…Read more
The Baseline command is intended to make it easy to turn any preexisting production database into a Flyway database so that, subsequently, versioned migrations can then be applied to it, bringing greater stability and predictability to database deployments.Read more
When processing a query in PostgreSQL that requires more memory than it's configured to allocate, data will be spilled to disk to complete the query operations. This can introduce performance bottlenecks. Redgate Monitor now includes recommendations for PostgreSQL that warn you when a spill occurs and will help you understand…Read more
If you need the current version of your Flyway database, and a history of the changes that were applied to build that version, then the info command is the place to go. It allows you to review applied and pending migrations, track migration status, and troubleshoot any issues that may…Read more
