Where each one falls short

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

RisingWave

  • Anything that does not fit SQL, such as custom windowing, complex event processing or heavy stateful logic, still needs Flink, so RisingWave often adds a system rather than removing one
  • The Apache 2.0 community edition excludes premium features behind a licence key, and which capabilities sit on which side of that line moves between releases, so a self-hosted plan can be invalidated by an upgrade
  • Long-running materialised views accumulate state in object storage, and cost and recovery time grow with retention in ways that are hard to forecast before you are in production
  • The Postgres compatibility is protocol level; it is not a transactional Postgres and using it as a general purpose database, with point updates or high write concurrency, goes badly
  • It is a comparatively young venture-funded project competing with Flink, Materialize and warehouse-native streaming, and the ecosystem of connectors, operators and third-party expertise is much thinner

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription
  • More resource-intensive than lightweight editors such as Sublime Text
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead
  • Startup time can be slower than simpler text editors on older hardware
