# remove_ingestion_lock

This lambda is responsible for removing a lock file associated with the UPC of the Product that is being ingested.

## Rational

We want to handle scenarios where two DDEX deliveries for the same UPC are ingested at the same time. We need to make sure that in these cases we prevent updating metadata until the previous one is finished as this may cause undesired behaviour. 

## Business logic

This lambda will execute after all metadata for an ingest has finished being updated and delete the lock file for a given UPC
