[GitHub] [arrow] tdcmeehan commented on pull request #37528: GH-37527: [Java] Allow FlightInfo#Schema to be nullable for long-running queries

tdcmeehan commented on PR #37528:
URL: https://github.com/apache/arrow/pull/37528#issuecomment-1703611295

   My 0.02 cents: as a user of Arrow, it's not obvious that I should represent a missing schema as a new `Schema` with a 0-length list of fields.
   
   I tried to browse the codebase for conventions I could learn from, and saw `PollInfo` as a source of inspiration: nullable fields are simply passed in null references, and they're exposed externally as Optional absent.  Please let me know if I misjudged this project's conventions!
