MySQL-Diff Sharp

MySQL-Diff Sharp is a rewrite in C# of the original CLI script made in Perl for comparing the schemas of two MySQL/MariaDB databases and generating diff sql.

Why

Why recreate the original Perl CLI in C#? Becouse the original needs Perl to run, which is painfull. This rewrite is a standalone executable that is easy to import into any CI/CD pipeline or docker containers. It also makes use of parallel CPU threads to speed up things, while the original CLI tool uses mysqldump. This project has no external dynamic dependecies such as the original Perl implementation.

Summing up reasons

  • no dependency on mysql nor mysqldump cli tools
  • parallel table dumping based on available CPU cores for threads
  • precompiled REGEX (yeah, C# allows us to compile REGEX for REALLY fast matches)
  • compiled to native speed, blazing fast startup times and low memory usage

Prerequisites

Just grab the binary for your own os from the release pages. This tools is self-container

Building

To build the app just make sure you have dotnet >= 10 and then:

dotnet publish -c Release
