xiaohui0318 commented on issue #9528: How do I keep a dimension where all the values are empty？？？ URL: https://github.com/apache/druid/issues/9528#issuecomment-600949899 I found a way, in a middlemanager configuration and set druid.Generic.UseDefaultValueForNull=false(single-server/micro-quickstart), and then change the null to "",this dimension into the druid; After I modify the druid middlemanager on line in this way, but it does not take effect. Do I need to modify other configurations?
