> DSL SQL: Public classes/methods should not expose/use calcite types
> -------------------------------------------------------------------
>
> Key: BEAM-2442
> URL: https://issues.apache.org/jira/browse/BEAM-2442
> Project: Beam
> Issue Type: Improvement
> Components: dsl-sql
> Reporter: Luke Cwik
> Assignee: James Xu
> Labels: dsl_sql_merge
> Fix For: Not applicable
>
>
> Calcite is an internal implementation detail of how Beam SQL is operating. To
> prevent a hard dependence on Calcite, public methods and classes should not
> rely on consuming/producing Calcite types.
> For example, BeamSqlRecordType uses org.apache.calcite.sql.type.SqlTypeName
> instead of using the Java SQL types
> (https://docs.oracle.com/javase/8/docs/api/java/sql/Types.html).
> This task is to create an ApiSurfaceTest to help find, fix, and prevent
> org.apache.calcite.* from being exposed. Example ApiSurfaceTest:
> https://github.com/apache/beam/blob/367fcb28d544934797d25cb34d54136b2d7d6e99/sdks/java/core/src/test/java/org/apache/beam/SdkCoreApiSurfaceTest.java
