I am experimenting with implementing a price drop feature. Can I register some document's fields and trigger some sort of events if the values change in those fields?
For example: 1. Price of itemX is $10 2. Say the price changes to $17 or $5 (increases or decreases) when the new data loads. 3. Trigger an event to take an action on that change, like send out an email. I believe this is somewhat similar but not the same as the percolator feature in elasticsearch. -- Thanks, -Utkarsh
