Description
Today, even though all commit metadata is written to the timeline in avro, `HoodieCommitMetadata` and its subclass `HoodieReplaceCommitMetadata` still need to be converted to json because of its legacy usage in code all over the place. Even though the cost of json-avro conversion is minimal (2.7ms for 1mb commit metadata), we would like to eliminate its usage altogether.
