This option can be activated if you need to update critical data at a higher frequency than the maximum default capacity of Sensefuel (every 2h).
For instance, you need your prices, availability, promotions to be updated in Near Real Time when Sensefuel download your catalog CSV/XML file (and eventually local inventory too) without waiting for the full compilation process.
You define with your Customer Success Manager what data needs to be considered as critical.
If you are interested, please contact your Customer Success Manager.
Note: this option is automatically activated when you are using the Catalog API.
