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

Mailchimp

  • The free plan allows 250 contacts and 500 sends a month, with a 250 daily cap
  • Price is driven by contact count, so the list growing raises the bill regardless of how much you send
  • Send allowances are a multiple of contacts, 10x on Essentials and 12x on Standard, so a large list with heavy sending forces a tier change
  • Essentials allows 3 seats and Standard 5; unlimited seats need Premium at $350 a month
  • The headline $13 and $20 prices are for 500 contacts, not a flat rate
