Deleting All Keys in Redis Using Golang (Detailed Guide w/ Code Examples)

Use Case(s)

The most common use case for deleting all keys from a Redis database using Golang is to clear the database during testing or development. It can also be useful when you want to flush stale data from your database.

Code Examples

1. Using Go-Redis package:

The go-redis package provides the FlushDB function that removes all keys from the currently selected database.

package main

import (
	"github.com/go-redis/redis/v8"
	"context"
)

func main() {
	rdb := redis.NewClient(&redis.Options{
		Addr:     "localhost:6379",
	})

	err := rdb.FlushDB(context.Background()).Err()
	if err != nil {
		panic(err)
	}
}

In the above code, we create a new client and connect to our local Redis server. Then we call the FlushDB function to delete all keys.

Best Practices

• Do not use this operation in a production environment as it will remove all the keys from the current database which can lead to loss of important data.

Common Mistakes

• Not checking the return error of the FlushDB function. It is always a good practice to handle errors in your code.

FAQs

Q: Can I use the FlushAll function instead of FlushDB?

A: Yes, but be aware that FlushAll will remove data from all databases in the Redis instance, not just the currently selected one.
