We need to add isnone() function that should return True if column or literal is empty (null / None) or False otherwise

Example usage:

dc.mutate(test=isnone("value"))

Questions: how to implement this for Clickhouse as there we currently don't support nullable columns. For now this can only work for SQLite.
