key takeaway : redis solves following issues : #1 minimize the cost by not just adding more computing power, databases, Redis can achieve same workload using much less servers # 2 support adding new features and stay flexible by using flexible data structures #3 how to keep it fast by not merely adding physical mysql databases but by using redis Redis features: #1 fast, #2 flexible data structures it can save #3 extensibility ( f.x you can add search module to turn redis into mini google)
