How to store java objects to Parquet format file

[Selina Tech]

Hi, All:

     I just start to study Parquet format. I need to store my java object
to Parquet format file at AWS S3. I know I could store the java objects to
a CSV format and then convert it to a CSV file to Parquet file. Can any API
help to store the java objects directly to Parquet file. Or is there any
better way?


Sincerely,
Selina
