AWS ElastiCache Limits and general questions
0
Hi AWS,
- What if each key value pair is storing 100mb of data?
- How much maximum key value pair is allowed and any restriction?
- Does it use memory for cache from application server or from the cache server?
Also can you please share the architecture diagram?

ElastiCache is a managed in-memory data store service that supports two engines: Redis and Memcached.

concepts are very similar but if we talk about redis
- not have a strict limit on the size of a key-value pair, it's generally recommended to keep them smaller for better performance but if you need to store 100MB no problem you can store
- Redis does not have a strict limit on the number of key-value pairs. The actual limit depends on the memory available in your cache node or cluster
- ElastiCache uses memory from the cache server, not from the application server. Your application server connects to the ElastiCache cluster to store and retrieve data, but the actual data resides in the memory of the cache server.
there is no specific architecture for elasticache it depends on you app architecture
