Action

Why this helps
Changes in document mix or intake volume are difficult to see without repeating queries over consistent periods.
- Compare periods using fields present in the table.
- Review trends without rewriting the query each time.
- Keep operational changes visible in a concise report.
Setup
Build it in a few focused steps.
- 1Connect Affinda and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, or describe it to Notis in plain language.
- 3Specify the table, available date field, category, and periods to compare in the query instruction.
- 4Choose a notis_cron schedule and select where run reports should go.
- 5Test with one run and verify the date boundaries and grouping.
Questions about this workflow
Can it explain why a trend changed?
It can summarize returned records. Explanations beyond the available data require additional context.
What if there is no usable date field?
A time-based trend needs dates in the table. Use another grouping or add a date value to the stored data.
