Hi all, As of Kudu 1.3, multi-word flags can use a dash '-' separator in lieu of the underscore '_' separator. For example, --memory_limit_hard_bytes can now be specified as --memory-limit-hard-bytes, or even --memory_limit-hard_bytes. Of the people I've talked to, most seem to prefer dashes to underscores in flag names, since that's been the Unix norm for a long time.
Going forward, I'd like to propose that we document flag names using dashes wherever possible. We would continue accepting underscores indefinitely, since to stop doing so would break compatibility. For the most part, this means incrementally switching the documentation to use dashes, and getting glog to output dashes in --help output. Any thoughts? - Dan
