Parallel MySQL Row Count

A simple tool for anyone who might need to count MySQL database rows accurately and with a high degree of parallelism. Useful for counting rows in large databases and comparing the output.

You can specify the configuration file by setting the following environment variable: ROWCOUNT_CONFIG=<config file>. Defaults to rowcount-config.yaml

The output of the program is stored in the output file and is sorted by database.tablename. This can be used to compare against executions on other databases. i.e. diff <output1> <output2>

⚠️ If you run this with a high number of workers in will load up your database ⚠️ ⚠️ Don't run on a live production database if you care about performance ⚠️

Example configuration options:

user: "row_count"
password: "secret_password"
address: "10.12.55.4:3306"
net: "tcp"
