The short version

  • Each has a real cost: Eclipse IDE startup time and UI responsiveness lag behind newer editors like VS Code.; Memcached no persistence at all: restart a node and its cache is gone, which every design must assume
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), Memcached covers In-memory key-value cache.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eclipse IDE

  • Startup time and UI responsiveness lag behind newer editors like VS Code.
  • Plugin quality and compatibility can be inconsistent across versions.
  • Modern language support (e.g. for web frameworks) is weaker than dedicated tools.
  • Configuration and workspace setup has a steeper learning curve for newcomers.

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Answered from the vendors’ own pages

Eclipse IDE: Is Eclipse IDE free to use, including commercially?

Yes, Eclipse is released under the Eclipse Public License 2.0, a free and open-source license that permits commercial use with no purchase required.

Extensions are installed from the Eclipse Marketplace, which hosts over 1,300 solutions spanning tools, languages, IoT support, and RCP applications, using drag-and-drop installation via the Marketplace Client.

Source
Memcached: Memcached or Redis?

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

Eclipse IDE: What license do Eclipse Marketplace plugins use?

Marketplace listings can be filtered by license type, including EPL, GPL, Apache 2.0, and MIT, since individual plugin authors choose their own licensing terms.

Source
Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.

Eclipse IDE: Where can I get help with Eclipse?

Support channels include community forums, project office hours, and a contact page maintained by the Eclipse Foundation, in addition to the official Eclipse Platform help documentation.

Source
Eclipse IDE: Is Eclipse limited to Java development?

No, while Eclipse's Java Development Tools are its best-known feature, the plugin architecture and marketplace extend it to C/C++, PHP, JavaScript, and many other languages.
