  • Each has a real cost: ClickHouse limited multi-row atomic transactions and expensive UPDATE/DELETE operations unsuitable for transactional systems; greytHR published starting price of INR 2,495/month covers only up to 50 employees, so larger companies must move to a higher, unpublished tier

Where each one falls short

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

ClickHouse

  • Limited multi-row atomic transactions and expensive UPDATE/DELETE operations unsuitable for transactional systems
  • Requires upfront schema design discipline with MergeTree engine choices and sort/partition keys
  • Experimental vector search support, not production-ready for vector operations
  • Different query syntax from standard SQL requiring migration planning
  • Limited JOIN capabilities compared to traditional relational databases
  • Migration complexity with 2-4 weeks estimated for data type mapping and query translation

greytHR

  • Published starting price of INR 2,495/month covers only up to 50 employees, so larger companies must move to a higher, unpublished tier
  • The platform serves 34,000+ companies and its entry tier is scoped by headcount rather than by feature set, meaning growth past 50 employees forces a plan change
