Re: [druid-user] why druid treat json array as a single value not a multi-value

Imho, this might be somewhere between a bug and right. It is the current design, afaict. I ingested a field as an MVD, some with one value, some with multiple, and in queries, the results are formatted as an array, or as a single (non-array) value. I think this issue gives some background on the design - https://github.com/apache/druid/issues/7525
