redisTools is a program written in Go for analyzing all the items in a Redis server. I created this program as a way of figuring out what types of data were taking up the most space in a Redis server.

You'll need a MySQL database for the program to use. The program will automatically take care of any table creation.

You'll need to setup the following environment variables:

export DB_CONNECTION_STRING=someuser:password@tcp(localhost:3306)/DatabaseName?charset=utf8&parseTime=true
export REDIS_DATA_SERVER=localhost:6379

go build -o bin/redisTools

redisTools keys iterator
redisTools delete pattern

This command fills the redis_keys table with the key and size of every item in your Redis server.

iterator - This represents the iterator that Redis returns when performing a SCAN command. You can use this iterator as a way of picking up where you left off if you need to exit the program at any time. If you don't provide the iterator, then the program will start from the beginning key REDIS SCAN 0

Example

redisTools keys 3921

This would start the SCAN command at iterator 3921

This command allows you to delete all keys matching a pattern. The delete command does not rescan Redis. Instead, it uses the keys that have been recorded into your redis_keys table.

pattern - The pattern you want used when searching redis_keys for a match. The pattern will be used in a like operator against the name field in redis_keys.

Example:

redisTools del '%profile'

This would delete every key ending in profile
