    Description

      Currently the create collection coordinator retrieves collection information through the catalog cache that in turn relies on the sharding catalog client to retrieve this data. Since the catalog cache uses a combination of nearest read preference and snapshot read concern it could read stale data from a secondary node of the CSRS. If this happen the create collection coordinator would wrongly assume that the collection has not been committed yet.
