Turn a Slack reaction into a data follow-up
Mark a data question with a reaction and let Notis handle the ClickHouse check and thread summary.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Why this helps
Data questions can get buried in busy channels when no one has time to investigate them right away.
- Creates a lightweight signal for which questions deserve investigation.
- Keeps the follow-up connected to the original message.
- Reduces reliance on remembering to return to an older thread.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickHouse to Notis once through the portal.
- 2Create an automation in the portal, or describe the workflow to Notis in a conversational channel.
- 3Give Notis one instruction to treat a chosen reaction on a data question as a request to query ClickHouse and summarize findings in the thread.
- 4Select Message Reaction Added as the trigger and choose a channel for run reports.
- 5Test by adding the chosen reaction to a real message containing a clear, answerable data question.
Questions about this workflow
Can any reaction start the investigation?
Tell Notis which reaction should signal a follow-up. The trigger supports optional channel and emoji filtering.
What kind of messages should get the reaction?
Use it for messages that state a clear data question. Ask Notis to clarify when the question lacks a metric or period.
