Reducer.sh - A Powerful MySQL/Percona/MariaDB Testcase Simplification/Reducer Tool

Reducer.sh is a powerful MySQL/Percona/MariaDB testcase simplification tool. It reduces large amounts of SQL quickly - often times down to just a few lines/hundreds of bytes, and that from a start input of 10-100K (or more) lines of complex SQL! A single-threaded testcase with a few million lines can often be reduced to 5 lines in a few hours. It is also the first (and only known) tool in the world which has true multi-threaded SQL testcase reduction.
It has been used to reduce testcases for thousands of bugs:
