> Flink is based on S3AInputStream.java to select datas stored in Tencent COS,
> it will call the getObject function of AmazonS3Client.java.
> Now, Tencent COS have already support to pushdown the CSV and Parquert file
> format.
> In these cases, using getObject to select datas will wastes a lots of
> bandwidth.
> So, I think Flink SQL should support S3 Select, to reduce the waste of
> bandwidth.
