Redis › Redis vs Memcached
How would you decide between Redis and Memcached for a large scale application with a purely simple, high volume string caching requirement and no need for advanced features?
AdvancedAnswer
You would benchmark both under a realistic workload closely matching your actual traffic patterns, weigh Memcached's potentially higher raw throughput for simple operations against Redis's additional operational value like built-in replication and persistence which might simplify your overall infrastructure even if you do not currently need Redis's more advanced data structures, and consider your team's existing familiarity and operational experience with each option.
