naruepanart / redis-bitfields

Demonstrates usage of Redis bitfields to store and retrieve voting information for citizens.

Redis Bitfield Example In Golang

This Go program demonstrates the usage of Redis bitfields to store and retrieve voting information for citizens. Each citizen is assigned a unique ID, and their vote is stored as a bit in a Redis bitfield.

Prerequisites

Make sure you have Go installed on your machine. You also need a Redis server running and accessible.

go get -u github.com/go-redis/redis/v8

Usage

1. Clone this repository:

git clone https://github.com/naruepanart/redis-bitfields.git

2. Navigate to the project directory:

cd naruepanart/redis-bitfields

3. Update the Redis server details in the main.go file:

const (
	redisAddress  = "your-redis-address"
	redisPassword = "your-redis-password"
	cacheKey      = "vote"
)

4. Run the program:

go run main.go

The program will generate a random Citizen ID and Vote Number, set the corresponding bit in the Redis bitfield, and then retrieve and print the bit value.

Configuration

• redisAddress: Address of the Redis server.
• redisPassword: Password for connecting to the Redis server.
• cacheKey: Redis key used for storing bitfield data.

Functions

• getRandomNumber(min, max int) int: Generates a random number between min and max (inclusive).
• setBitField(client *redis.Client, cacheKey string, position int, value int) error: Sets the bit at the given position in the Redis bitfield.
• getBitField(client *redis.Client, cacheKey string, position int) (int64, error): Retrieves the bit at the given position from the Redis bitfield.
