> The following query results in a column name of "shot_id" instead of the expected "x".
> SELECT shot_id as x FROM values.parquet WHERE step = 'RPCurve_001'
> The strange thing is, if I modify the query, like adding a limit clause, it is working:
> SELECT shot_id as x FROM values.parquet WHERE step = 'RPCurve_001' LIMIT 1000
> [^values.parquet]
