PartitionSorter (venice API)

java.lang.Object
- com.linkedin.venice.hadoop.spark.datawriter.partition.PartitionSorter

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator<org.apache.spark.sql.Row>
```
public class PartitionSorter
extends java.lang.Object
implements java.util.Comparator<org.apache.spark.sql.Row>, java.io.Serializable
```
Sort the rows based on the key and value in ascending order using unsigned byte comparison.
- The sorting on the key is the same as what RocksDB and Shuffle-Sort in MapReduce use.
- The sorting on the value is to make SparkPartitionWriter be able to optimize the de-duping of values.
