How can I handle errors in Go when using Redis?

In Go, you can handle errors from Redis operations by checking the error returned by the Redis client methods. For example, after a Set or Get operation, you should check if the error is not nil.

Can you show me a code example?

Sure! Here's a simple example:

result, err := client.Get(ctx, "key").Result()
if err != nil {
    if err == redis.Nil {
        fmt.Println("Key does not exist")
    } else {
        fmt.Println("Error getting key:", err)
    }
} else {
    fmt.Println("Value: ", result)
}

What if I want to retry the operation on error?

You can implement a retry mechanism using a loop. For example, you can try the operation a few times before giving up. Here's a basic structure:

for i := 0; i < maxRetries; i++ {
    result, err := client.Get(ctx, "key").Result()
    if err == nil {
        fmt.Println("Value: ", result)
        break
    }
    time.Sleep(time.Second) // wait before retrying
}
