    Study Notes

    Scaling and Optimization Experiences

    • Successfully led team migration from IBM MQ to Kafka at REI.

    • Ensured scalability by carefully planning Kafka's message processing for increased message volume without performance degradation.

    • This ensured the system could handle growth without impacting speed or reliability.

    • Integrated Redis as a caching layer to improve system performance by reducing database load.

    • Optimized Redis configuration to reduce latency and minimize memory footprint.

    • Focused on data retrieval speed and efficient memory usage under high load.

    • Optimized database performance by implementing indexing strategies during retail-stores project.

    • Improved query performance and allowed the system to scale with larger datasets without delays.

    • Constantly focused on maintaining efficiency while handling increases in demand – crucial principles of scaling and optimization.
