[jira] [Commented] (HUDI-8333) Leverage Functional index only for columns which are order preserving in the reader path

    [ https://issues.apache.org/jira/browse/HUDI-8333?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17894046#comment-17894046 ] 

Y Ethan Guo commented on HUDI-8333:
-----------------------------------

Functional Index works with functions on a column that is not order-preserving.  So there is no limitation of preserving orders.
