Never Forget Your Data Structure
What tables do you actually have in ClickHouse? Every Monday, Notis reminds you so you can reference them when building automations.

Why this helps
Your ClickHouse has data, but you forgot exactly what tables exist or what they're called. You waste time asking others or digging through old notes.
- Weekly reminder of all available ClickHouse tables keeps data awareness fresh
- Reference point for building new automations without guessing table names
- Discover new tables you might have forgotten about

- 1Connect ClickHouse to Notis.
- 2Ask Notis: 'Every Monday morning, list all my ClickHouse tables and send me a reminder.'
- 3Notis sets up the weekly schedule automatically.
- 4Pick email or Slack for the reminder.
- 5You'll get a list of all your tables with row counts every week.
Questions about this workflow
Does this show row counts and table sizes?
Yes. You get table name, row count, and disk usage so you know which tables are growing.
Can I request this on demand instead of weekly?
Absolutely. Tell Notis 'Send me my table list whenever I ask' and ping Notis in Slack or email anytime.
What if I only care about certain tables?
Tell Notis to filter, like 'Only show tables with names containing issues or metrics.'
