Installation and documentation

What is Dumpling?

Dumpling is a wrapper for mysqldump that uses sensible defaults, and provides a streamlined interface. Dumpling is designed to be as intuitive and simple to use as possible.

Dumpling still uses mysqldump internally, so it's 100% compatible. It also produces output which is much more diff-friendly than standard mysqldump.

What's wrong with mysqldump?

  • Outputs internal databases like mysql and information_schema which are useless in 99% of cases (and potentially dangerous when importing).
  • Extreme line length on extended INSERT statements causes havok for many text editors.
  • Diffing of extended INSERT statements is useless, because of line length, and unpredictable row order.
  • Leaves out important procedure and function information by default.
  • Command line interface is cluttered and inflexible; inclusion/exclusion of databases and tables is inconsistent and limited.
  • Raw binary data ruins portability & human readability.
  • Command line interface uses non-standard conventions for options and their values.
