ClickHouse now allows creating dictionaries without specifying any attributes.
Why it matters
This feature enables users to define dictionaries that have no attributes, which can be useful for certain use cases where only keys or the dictionary structure itself is needed without additional attribute data. It increases flexibility in dictionary creation and usage.How to use it
When creating a dictionary, simply omit the attributes list or provide an empty list. The dictionary will be accepted and created even if no attributes are specified.
