We could access the base type (wire format type) directly in SQL with [Row#getBaseValue](https://github.com/apache/beam/blob/7b890654e6bbfcab79a2f5677f1badd54bd444aa/sdks/java/core/src/main/java/org/apache/beam/sdk/values/Row.java#L424), but unfortunately Rows store logical types as the input type (in memory format type), so that wouldn't actually avoid a conversion. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
