/**
* HoodieKey consists of
*
* - recordKey : a recordKey that acts as primary key for a record.
* - partitionPath : the partition path of a record.
*
* NOTE: PLEASE READ CAREFULLY BEFORE CHANGING
*
* This class is serialized (using Kryo) as part of {@code HoodieDeleteBlock} to make
* sure this stays backwards-compatible we can't MAKE ANY CHANGES TO THIS CLASS (add,
* delete, reorder or change types of the fields in this class, make class final, etc)
* as this would break its compatibility with already persisted blocks.
