> Do ORC dictionary check at a finer level and preserve encoding across stripes
> -----------------------------------------------------------------------------
>
> Key: HIVE-7832
> URL: https://issues.apache.org/jira/browse/HIVE-7832
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 0.14.0
> Reporter: Prasanth J
> Assignee: Prasanth J

>
> Currently ORC dictionary check happens while writing the stripe. Just before
> writing stripe if ratio of dictionary entries to total non-null rows is
> greater than threshold then the dictionary is discarded. Also, the decision
> of using dictionary or not is preserved across stripes. This sometimes leads
> to costly insertion cost of O(logn) for each stripes when there are too many
> distinct keys.
