What is your experience with Redis?

I have been actively using Redis as a cache and message broker for two years.

As a cache, I used it for:

• Session data
• Results of resource-intensive queries
• Object metadata

I configured RDB persistence to save data in case of failures. Monitoring was done using Prometheus and Grafana, tracking hit/miss rate, latency, and memory usage. I optimized caching by setting the correct TTL and eviction strategy (allkeys-lru).

As a message broker, I used Streams to implement asynchronous data processing and distributed tasks.

# Example command to add a message to a stream
redis-cli XADD mystream * message "Hello from Redis"

I implemented consumer groups for distributed message processing and scaling.

I worked with Sentinel clusters to ensure high availability and automatic failover. I configured replication (master-replica) to increase reliability.

I used Redis in conjunction with:

• Python (library redis)
• Node.js (libraries ioredis or node-redis)
• Spring Boot (Spring Data Redis)

I participated in infrastructure planning using Redis, considering performance, scalability, and reliability requirements. I optimized Redis configuration (redis.conf) for specific tasks.
