The short version

  • Each has a real cost: ClickHouse limited multi-row atomic transactions and expensive UPDATE/DELETE operations unsuitable for transactional systems; Telegram end-to-end encryption applies only to Secret Chats; private and group Cloud Chats use server-client encryption, so Telegram holds the data
  • They diverge on capability: ClickHouse covers Column-oriented Storage, Telegram covers Cloud-based messaging.

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

Telegram

  • End-to-end encryption applies only to Secret Chats; private and group Cloud Chats use server-client encryption, so Telegram holds the data
  • Secret Chats are device-specific and are not part of the Telegram cloud, so they can only be read on the device they started on
  • Logging out destroys all of your Secret Chats
  • The Secret Chat self-destruct timer applies only to messages sent after the timer is set and has no effect on earlier messages
  • Telegram states screenshot detection cannot be guaranteed on some Android and Windows Phone devices, so screenshots of Secret Chats can be taken silently
  • Messages cannot be forwarded out of Secret Chats
  • The self-destruct timer in cloud chats covers media only, not text
