Often, you might need to delete specific hashes from Redis, like when data becomes obsolete or for regular cleanup operations. In Golang, you can use the DEL
command to remove these hashes.
Let's look at code examples using the go-redis/redis
package.
To delete a hash:
package main import ( "github.com/go-redis/redis/v8" "context" ) func main() { rdb := redis.NewClient(&redis.Options{ Addr: "localhost:6379", Password: "", // no password set DB: 0, // use default DB }) ctx := context.Background() _, err := rdb.Del(ctx, "your_hash_key").Result() if err != nil { panic(err) } println("Hash deleted") }
This example shows how to connect to a Redis server and delete a hash using the Del
method. Replace 'your_hash_key' with the key of your hash.
Del
function to ensure that the operation was successful.Close
function.Del
function may lead to silent failures where the hash is not deleted, but the program continues running.Q: Can I delete multiple hashes at once?
A: Yes, you can pass multiple keys to the Del
command like so: rdb.Del(ctx, "key1", "key2", "key3")
. Each key will be deleted from Redis.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
