ParquetWriteSupport

abstract class ParquetWriteSupport[T] extends WriteSupport[T] with Serializable

Parquet write support used by org.apache.parquet.hadoop.ParquetOutputFormat to write values to parquet output. User must provide record schema and a function which permits to write a used defined case class to parquet store with the record consumer and schema definition.

For case class value types, we provide a macro to generate the write support, please check com.twitter.scalding.parquet.tuple.macros.Macros.caseClassParquetWriteSupport
