Hello! I'm hoping someone can help me shed some light on how Hive deals with virtual columns. We are trying to implement some time travel features in a custom input format we're building and are considering the approach of adding a virtual column, but I haven't been able to find much information on Hive's implementation.
Any help or links on how we can add our own virtual column to a Hive table would be very appreciated! Thank you! Christine Mathiesen Software Development Intern BDP – Hotels.com Expedia Group
