This feature is necessary when the corresponding dimension/metric is a sparse column, and values are not present from the beginning of the indexation, but can be present later in time. During the interval of the datasource creation and the arrival of first values on this column , any query including the column currently fails. Would impact adding additional information on diemnsionSpec https://druid.apache.org/docs/latest/ingestion/index.html#dimensionsspec or metricsSpec https://druid.apache.org/docs/latest/ingestion/index.html#metricsspec -- This is an automated message from the Apache Git Service.
