Sound Familiar?

ClickHouse MVs are powerful but operationally painful

"Which MV broke?"

Dig through query_log, grep for exceptions, trace the cascade manually. Every. Single. Time.

"What depends on what?"

15 MVs, 3 databases, zero documentation. Good luck with that backfill.

"Why is it slow?"

Parts piling up? Memory pressure? You won't know until it's too late.

  • • Hope the docs are up to date

After

  • • One command: misclick graph
  • • Visual DAG of all dependencies
  • • Health status per table
  • • Click for metrics and DDL

Frequently Asked

Does MisClick write to my ClickHouse?
No. MisClick is read-only. It queries system.tables and system.parts for metadata. It never inserts, deletes, or alters data.
What credentials do I need?
A ClickHouse user with read access to system.tables and system.parts. No special privileges required. Use MISCLICK_CH_* env vars or CLI flags.
Where does MisClick run?
On your machine or your infrastructure. CLI runs locally; the server can run in Docker, Kubernetes, or anywhere that can reach ClickHouse over the native port (9000).
