This looks good to me! Can you get rid of the boost::option dependency and use the value -1 instead of boost::none? At the moment plasma doesn't depend on boost and I'd like to keep it that way unless there is a good reason to introduce it.
Also can you rebase the PR? There is a small conflict at the moment.

@pcmoritz Thanks for reviewing :) Changed boost::none to -1 and did a rebase to resolve the conflict. |

@zhijunfu Sorry, the other PR caused a merge conflict, can you rebase/merge so we can get this PR in? Thanks :) |

@pcmoritz Sorry for the long delay in reply, I just rebased the change on top of latest code. The build failures w/ parquet and tool-chain should be unrelated with the change. |

Unrelated to the content of this patch: could we regularize the variable name convention in this header and elsewhere in Plasma? Would help with readability
