Other in-memory caches

While DAX is an excellent choice for in-memory caching with DynamoDB, it is not the only option available. Depending on the requirements of the application, other caching data stores such as Redis or Memcached may be more suitable.

One of the primary considerations when choosing a non-DAX caching solution is the need to manage and implement the caching logic on your own. While DAX is fully managed (meaning that the caching logic is handled by AWS), Redis and Memcached require more involvement from the user. This can include setting up and configuring the cache cluster, implementing cache eviction policies, and monitoring cache performance.

Redis is a popular in-memory cache that provides a range of data structures, such as strings, hashes, lists, sets, and sorted sets, allowing for more complex data models than DAX. Redis also supports features such as pub/sub messaging, Lua scripting, and transactions. Redis is often used for real-time applications, such...
