[QUESTION] Why is TimestampBasedKeyGenerator part of hudi-utilities?

[Gurudatt Kulkarni]

Hi All,

All other key generators are part of hudi-spark
except TimestampBasedKeyGenerator, it causes issue while using just
hudi-spark directly in a spark job. Any specific reason for this? Can we
move this to hudi-spark module?

Regards,
