HERAUSFORDERUNGEN

Couchbase vs. Memcached

Memcached is a simple cache, while Couchbase is a scalable, persistent NoSQL database with advanced features.

  • HERAUSFORDERUNG #1

    Cold cache

    Memcached failures overload the RDBMS. Couchbase ensures high availability with automatic data replication.

    Memory storage

  • HERAUSFORDERUNG #2

    Limited features

    Memcache functionality limits use cases. Couchbase is multipurpose.

  • HERAUSFORDERUNG #3

    Skalierbarkeit

    Memcached scaling is complex and disruptive. Couchbase has auto-sharding and online rebalancing.

  • Challenge #4

    Monitoring

    Memcached lacks unified management. Couchbase offers a built-in admin console and APIs for streamlined cluster control.

Memcached frequently asked questions

Common questions and answers about memcached and Couchbase

Nothing. “memcache” is the software, “memcached” is the daemon program name. Most people now just say “memcached” for both due to naming convention and common usage.

Is it memcached (as in “I just cached it”) or is it memcache-dee? Both are used widely in technical circles, but if you hold to its UNIX roots, you would pronounce it “memcache-dee.

Couchbase once supported memcached-compatible buckets – still possible, but now deprecated and not recommended for new projects.

If you want memory-only storage, use an Ephemeral bucket. If you want memory-first with persistence to disk, use a Couchbase bucket.
