The short version

  • Each has a real cost: Eclipse IDE startup time and UI responsiveness lag behind newer editors like VS Code.; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), Thanos covers Global query.

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.

Thanos

  • Several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • The compactor is a common source of operational trouble and must not run twice against the same bucket
  • Query latency over object storage is meaningfully higher than local Prometheus
  • Object storage costs and API request charges become real at high volume

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.

Source
Thanos: Is Thanos free?

Yes, open source and CNCF-incubating. Costs are the object storage it uses.

Eclipse IDE: How do I extend Eclipse with plugins?

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
Thanos: Does Thanos replace Prometheus?

No. It runs alongside existing Prometheus servers, adding global query, deduplication and long-term storage.

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
Thanos: Thanos or VictoriaMetrics?

Thanos layers onto Prometheus using object storage and is the more established multi-cluster answer. VictoriaMetrics is a separate store aiming at lower resource use and fewer moving parts.

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.
