[jira] [Commented] (FLINK-8563) Support consecutive DOT operators

    [ https://issues.apache.org/jira/browse/FLINK-8563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16353571#comment-16353571 ] 

Shuyi Chen commented on FLINK-8563:
-----------------------------------

I think once we upgrade to 1.16, consecutive DOT operators will be supported without changing anything in Flink. But we should add unittests to capture this.

> We added support for accessing fields of arrays of composite types in FLINK-7923. However, accessing another nested subfield is not supported by Calcite. See CALCITE-2162. We should fix this once we upgrade to Calcite 1.16.
