Question: When to use Memcached vs Redis?

Answer

Memcached and Redis are both in-memory data stores, but they have some differences in terms of functionality and implementation. Choosing between them for a particular use case can depend on factors like data complexity, read/write operations, and scalability requirements. Here are some guidelines to consider:

  1. Data Complexity:
  1. Read/Write Operations:
  1. Scalability:

Here are some code examples to illustrate the basic usage of both Memcached and Redis:

# Memcached Python Example
import memcache

mc = memcache.Client(['127.0.0.1:11211'], debug=0)
mc.set("key", "value")
print(mc.get("key"))

In summary, choose Memcached if you need a lightweight, fast, and easy-to-scale caching solution that can handle high read/write loads. Choose Redis for more advanced data structures, write-heavy workloads or situations where data must be persisted beyond just caching.
