> We use rapidjson to print structs but don't use it to print collections (arrays and maps). We should switch to rapidjson also for collections to have a uniform approach.
> This is also needed if we want to support embedding structs and collections in each other, see [IMPALA-9551|https://issues.apache.org/jira/browse/IMPALA-9551].
