---------------------------------

             Summary: [SQL] Allow casting to complex types
                 Key: BEAM-4516
                 URL: https://issues.apache.org/jira/browse/BEAM-4516
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql
            Reporter: Anton Kedin


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 a fully ad-hoc specified
Row at the moment (Calcite 1.16).

Probably CREATE TYPE in Calcite 1.17 is worth looking at, it should support CAST
