Azure Cosmos what happens if partition key value is null

In Azure Cosmos I have selected partition key as City. But it is possible that this key can have a null also. In such a case. Will all the City with null be in one partition.

How will the partition be distributed in this case?

You can create. Null, Undefined, and empty string are treated as different values in Cosmos DB. 

new RequestOptions { PartitionKey = new PartitionKey(null) }

As 4c74356b41 mentioned There will be a separate partition and these values will go under that.

Fairly certain there is a hidden partition and all the documents without a partition key would go to that partition.

I recall reading this somewhere on SO answers\comments.
