Re: How to create user-defined data types in calcite?


Currently, user defined type is not supported in Calcite. But it's WIP,
please see https://issues.apache.org/jira/browse/CALCITE-2045. With this
PR, you can either use CREATE TYPE statement to define your own type or
define your new type in the JSON schema.

Thanks
