Sorry, I missed this.
We can't use byte ranges directly but we can use condition push down to
reduce download size.
We doesn't provide DSL to build condition yet (#29928) but the following
will work:
```ruby
require 'arrow-dataset'
s3_uri = URI('s3://bucket/public.parquet')
Arrow::Table.load(s3_uri, filter: [:equal, :column_name, 100]) #
"column_name == 100"
```
See https://arrow.apache.org/docs/cpp/compute.html for available functions.
