Community FAQ

Questions by product

Amazon ElastiCache FAQ

Can I self-host Amazon ElastiCache or is it strictly a managed AWS service?

Amazon ElastiCache is a fully managed service provided by AWS and does not support self-hosting. If you need a self-hosted Redis or Memcached solution, you would have to deploy and manage the cache servers yourself on EC2 or other infrastructure outside of ElastiCache.

Community insight informed by Reddit discussions

Does Amazon ElastiCache support offline or local caching when the network connection to AWS is lost?

No, ElastiCache requires a live network connection to AWS since it is a managed caching service running in AWS data centers. It does not provide offline or local caching capabilities on client devices or outside the AWS environment.

Community insight informed by StackOverflow discussions

Who owns the data stored in Amazon ElastiCache and what are the implications for data privacy?

Data stored in Amazon ElastiCache remains the property of the AWS account holder using the service. AWS acts as the data processor under their shared responsibility model, and customers are responsible for securing data access via IAM policies and encryption options. AWS does not access or use your data beyond operational needs.

Community insight informed by Forums discussions

Are there any API limitations or differences when using Redis or Memcached through ElastiCache compared to open-source versions?

ElastiCache supports most standard Redis and Memcached commands, but some features may be limited or unavailable due to the managed environment. For example, certain Redis modules or commands that require server-side extensions are not supported. Also, ElastiCache enforces some operational limits like max connections and memory usage based on node types.

Community insight informed by Hacker News discussions

What are the recommended migration or export paths if I want to move data out of Amazon ElastiCache?

For Redis, you can use the standard RDB snapshot export feature to backup and migrate data to another Redis instance. For Memcached, since it is an in-memory cache without persistence, migration typically involves application-level cache warming or data reload. ElastiCache supports automated backups for Redis but not Memcached.

Memcached FAQ

How complex is it to self-host Memcached in a production environment?

Self-hosting Memcached is relatively straightforward due to its lightweight design and minimal dependencies. It requires setting up the Memcached server on your infrastructure, configuring memory allocation, and ensuring network accessibility for your clients. However, you need to handle clustering and failover at the application level or via consistent hashing, as Memcached itself does not provide built-in replication or persistence features.

Community insight informed by Reddit discussions

Does Memcached support offline or persistent caching to survive server restarts?

No, Memcached does not support persistence or offline caching. All cached data resides in volatile memory and is lost if the server restarts or crashes. This design choice keeps Memcached extremely fast but means it is unsuitable for use cases requiring durable cache storage.

Community insight informed by StackOverflow discussions

What are the main API limitations of Memcached compared to Redis?

Memcached offers a simple key-value API with basic commands for storing, retrieving, and deleting data. Unlike Redis, it lacks support for advanced data structures such as lists, sets, sorted sets, hashes, and streams. It also does not provide features like pub/sub messaging, transactions, or Lua scripting. This makes Memcached ideal for straightforward caching but limits its applicability for complex data manipulation.

Community insight informed by Hacker News discussions

How can I migrate cached data from Memcached to Redis if I need more features later?

There is no direct export/import tool for migrating Memcached data to Redis because Memcached only stores simple key-value pairs in memory without persistence. To migrate, you would typically write a custom script that reads keys and values from Memcached and writes them into Redis. Note that you will lose any Memcached-specific expiration metadata and must adapt data formats if you want to leverage Redis data structures.
