> Many users want to understand what would be their avg record size in hudi
> storage. They need this so that they can deduce their bloom config values.
> 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.
> As of now, we could calculate the avg size from bytes written/records written
> from commit metadata.
