I will address it soon. > > One somewhat related question. Does the hive catalog (not necessarily hive metastore) support cross catalog views now? `HiveCatalog` itself doesn't have constraints on that, because views and their expanded query are just data passing thru `HiveCatalog` on read/write and `HiveCatalog` won't manipulate them, so it's totally up to the planner that whether it can parse and support those cross-catalog views. I'm not sure whether users would find cross-catalog views useful, maybe we can listen to user feedbacks after releasing 1.9? I don't think it need to happen in 1.9. @lirui-apache can help and share how we build a `HiveAnalyzer` in Blink to support Hive view expanded query on view creation and parsing it upon read. Maybe you guys can talk offline on that.
