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. > [C++] DICTIONARY_REPLACEMENT neither read nor written > ----------------------------------------------------- > > Key: ARROW-11419 > URL: https://issues.apache.org/jira/browse/ARROW-11419 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Reporter: Antoine Pitrou > Priority: Major > Fix For: 4.0.0 > > > The IPC format has a feature field DICTIONARY_REPLACEMENT to advertise the > use of dictionary replacement but it is not emitted by the IPC writer, even > if dictionary replacement occurred. -- This message was sent by Atlassian Jira (v8.3.4#803005)
