The aggregation stage $shardedDataDistribution returns null for both ownedSizeBytes and oprhanedSizeBytes fields when there are no documents on that collection.
> db.adminCommand({shardCollection: "dba.collA", key: {x:1}})
> db.aggregate([{$shardedDataDistribution:{}},{$match:{ns:{$eq:"dba.collA"}}}])
[
{
ns: 'dba.collA',
shards: [
{
shardName: 'shard02',
numOrphanedDocs: 0,
numOwnedDocuments: 0,
ownedSizeBytes: null,
orphanedSizeBytes: null
}
]
}
]
We should return 0 instead of null for those cases.
