Shayang Zang commented on BEAM-2990:
------------------------------------

Calcite does support Array/Map ... non-scalar data types as listed in the link: http://calcite.apache.org/docs/reference.html#non-scalar-types

Use case can be found in their JdbcTest.java: https://github.com/apache/calcite/blob/master/core/src/test/java/org/apache/calcite/test/JdbcTest.java
