Why this helps
Repeated documents can create noisy counts and extra review work when duplicates are hard to spot.
- Surface possible duplicate candidates for review.
- Apply consistent matching criteria.
- Avoid treating a suspected duplicate as an automatic deletion.
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 and fields that define a possible duplicate, then ask Notis to query and summarize matching groups.
- 4Choose a notis_cron schedule and select where run reports should go.
- 5Test with one run and verify candidates before acting on them.
Questions about this workflow
Does it delete duplicate records?
