title: Writing parquet files to S3 using AWS java lamda
body: <p>I'm writing AWS lambda that reads protobuf obejcts from Kinesis and would like to write them to s3 as parquet file.  </p>
  
  <p>I saw there's a implementation of ParquetWriter for protobuf called ProtoParquetWriter, which is good. My problem is that ProtoParquetWriter expects a Path in its constructor.  </p>
  
  <p>What's the right way to do that without saving the content as parquet file, assuming I'm not using the file system at all?</p>
