ATTACHMENT ID: 12694605 - PreCommit-HIVE-TRUNK-Build
> Move parquet serialize implementation to DataWritableWriter to improve write
> speeds
> -----------------------------------------------------------------------------------
>
> Key: HIVE-9333
> URL: https://issues.apache.org/jira/browse/HIVE-9333
> Project: Hive
> Issue Type: Sub-task

>
> The serialize process on ParquetHiveSerDe parses a Hive object
> to a Writable object by looping through all the Hive object children,
> and creating new Writables objects per child. These final writables
> objects are passed in to the Parquet writing function, and parsed again
> on the DataWritableWriter class by looping through the ArrayWritable
> object. These two loops (ParquetHiveSerDe.serialize() and
> DataWritableWriter.write() may be reduced to use just one loop into the
> DataWritableWriter.write() method in order to increment the writing process
> speed for Hive parquet.
> In order to achieve this, we can wrap the Hive object and object inspector
> on ParquetHiveSerDe.serialize() method into an object that implements the
> Writable object and thus avoid the loop that serialize() does, and leave the
> loop parser to the DataWritableWriter.write() method. We can see how ORC does
> this with the OrcSerde.OrcSerdeRow class.
> Writable objects are organized differently on any kind of storage formats, so
> I don't think it is necessary to create and keep the writable objects in the
> serialize() method as they won't be used until the writing process starts
> (DataWritableWriter.write()).
> We might save 200% of extra time by doing such change.
> This performance issue was found using microbenchmark tests from HIVE-8121.
