> Many users want to understand what would be their avg record size. As of now, there is no easy way to fetch record size for the end user. Even w/ hudi-cli, we could decipher from commit metadata, but we need to make some rough calculation. So, it would be better if we store the avg record size w/ WriteStats (total bytes written/ total records written) , as well as in commit metadata. So, in hudi_cli, we could expose this info along w/ "commit showpartitions" or expose another command "commit showmetadata" or something.
