Description
Is your feature request related to a problem or challenge? Please describe what you are trying to do.
In the table provider for lance in the scan method I sometimes have to do a small amount of I/O to load dataset metadata if the metadata is not already in the cache. The scan method is async so I assume this is ok. However, I use spawn_blocking to trigger this I/O and it fails because the runtime is not active.
Describe the solution you'd like
The runtime should be attached before calling scan.
Describe alternatives you've considered
Currently I work around this by forcing the metadata to be cached before creating the table provider but this is inconvenient.
Additional context
Can provide additional details (stack traces, lance reproducers, etc.) on request.
