Known Issues

  • If using the Apache Druid data source and a Categorical Trait is created for one or more properties, please make sure that the MSO > Settings > Easy Answers > Quantitative Views > Bucketing Type is set to “Value”. The Apache Druid data source does not support “Percentage” as a Bucketing Type.

  • If using the Apache Druid data source and a Sortable Trait is created for one or more properties, a Druid limitation exists that only allows column sorting of time-based properties. See https://druid.apache.org/docs/latest/querying/sql/#order-by.
