Gerrie is a data and information crawler for Gerrit, a code review system developed by Google.

Gerrie uses the SSH and REST-APIs offered by Gerrit to transform the data from Gerrit into a RDBMS. Currently only MySQL is supported. After the transformation the data can be used to start simple queries or complex analysis. One usecase is to analyze communites which use Gerrit like TYPO3, Wikimedia, Android, Qt, Eclipse and many more.
