This example demonstrates how to set up a Redis cluster with Sentinel and implement a probabilistic cache mechanism using Node.js and the ioredis
library.
-
Clone this repository to your local machine.
-
Install the required dependencies by running the following command:
yarn
-
Start the Redis cluster and Sentinel services using Docker Compose:
docker-compose up
This will start three services:
redis-master
,redis-slave
, andredis-sentinel
, forming a Redis cluster with Sentinel. -
Run the Node.js script to execute the cache example:
node index.ts
The script will use the
ioredis
library to interact with the Redis cluster and demonstrate the probabilistic cache mechanism.
The provided Node.js script (index.ts
) demonstrates a probabilistic cache mechanism that attempts to cache a value with a predefined time-to-live (TTL) and a probability of updating the cache based on the remaining TTL.
