[jira] [Commented] (ARROW-11419) [C++] DICTIONARY_REPLACEMENT
neither read nor written
[ https://issues.apache.org/jira/browse/ARROW-11419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17276060#comment-17276060 ]
Micah Kornfield commented on ARROW-11419:
-----------------------------------------
this is accurate, I thought I had a Jira to track implementation. I added the enum early because we were reaching 1.0 and it would have been a forward compatible change to add it. So there is not implementation to date.
