> The TableSchemaResolver can have varied performance depending on the last
> commit to the table. The code will currently try to inspect log files with
> only deletes for example which will not yield a schema and then we must
> inspect another file. In the worst case, you can iterate through all the
> files and still not find a valid schema.
> This can be updated to first ensure the commit has a non-zero number of
> inserts or updates, then inspect files that have non-zero inserts or updates
> only.
