Anton Kedin updated BEAM-4516:
------------------------------
Description:
Currently CAST is parsed in the main Calcite's Parser.jj. When parsing the
target type parameter it only supports primitive types or MULTISET). It's
impossible to cast to an inline fully specified Row type at the moment (Calcite
1.16).
Probably CREATE TYPE in Calcite 1.17 is worth looking at, it should support CAST
