Review comment:
yes. so by preserve commit metadata, implicitly we mean to preserve
every commit metadata(record key, partition path, commit time, commit seq no)
except filename. Every other meta field should be carry forwarded from old
record, but filename has to represent the file where the record actually
exists.
