So the way entities in Azure Table Storage are structured is that they only have columns they have been given a value to.
e.g:
PartitionKey | RowKey | SomeData | SomeTimestamp
PartitionKey | RowKey | SomeData
Second "row" does not have any data in "SomeTimestamp"
How can I build a filter query that will include entities without the given column?
i.e: I want "$filter='SomeTimestamp gt yesterday'" to return both rows, not just the one with data in "Sometimestamp"
