I am looking for guidance (read examples) on tuning ORC settings for my data. I see the documentation that shows the defaults, as well as a brief description of what it is. What I am looking for is some examples of things to try. *Note: I understand that nobody wants to make sweeping declaring of set this setting without knowing the data* That said, I would love to see some examples, specifically around:
orc.row.index.stride orc.compress.size orc.stripe.size For example, I'd love to see some statements like: If your data has lots of columns of small data, and you'd like better x, try changing y setting because this allows hive to do z when querying. If your data has few columns of large data, try changing y and this allows hive to do z while querying. It would be really neat to see some examples so we can get in and tune our data. Right now, everything is a crapshoot for me, and I don't know if there are detrimental affects that may make themselves known later. Any input would be welcome.
