The short version

  • Each has a real cost: Refact requires configuration for optimal performance; StarRocks self-hosting is a genuine operations job: frontend and backend node roles, tablet distribution, compaction and materialised view refresh all need an owner, and there is no small-team-friendly single-binary mode.
  • They diverge on capability: Refact covers Autonomous agent workflows, StarRocks covers Cost-based optimiser.
  • Prices and features above were last checked on 31 August 2026.

  • Enterprise development with data privacy requirementsnot StarRocks

StarRocks

  • Querying an Iceberg lakehouse directly without copying data into a proprietary warehouse formatnot Refact
  • Replacing a ClickHouse deployment that has become unmanageable because every new question needs another denormalised tablenot Refact
  • Real-time analytics fed by change data capture where rows must be updated in place rather than appendednot Refact

Where each one falls short

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

Refact

  • Requires configuration for optimal performance
  • On-premise deployment adds operational complexity
  • Free tier limited by daily agent request quota
  • Coin system adds complexity to cost calculation

StarRocks

  • Self-hosting is a genuine operations job: frontend and backend node roles, tablet distribution, compaction and materialised view refresh all need an owner, and there is no small-team-friendly single-binary mode.
  • CelerData is by far the dominant contributor despite Linux Foundation stewardship, so the practical roadmap risk is the same as any single-vendor open source project.
  • It inherits a MySQL-flavoured SQL dialect from its Doris ancestry, so queries written for PostgreSQL, Snowflake or Trino need rewriting rather than porting.
  • Ecosystem support is thinner than ClickHouse or Trino: fewer client libraries, fewer managed hosting options and a much smaller pool of engineers who have run it in production.
  • Memory pressure under concurrent large joins is a common production failure, and the tuning knobs for query memory limits are unforgiving compared with a cloud warehouse that just scales.
