PR Description to use:
## Summary
This PR adds documentation and examples for using
`calcite_connection_properties` in YAML SQL transforms, addressing issue #36614.
**Changes:**
- Added new example file `sql/sql_calcite_connection_properties.yaml`
demonstrating how to configure PostgreSQL-specific SQL functions in YAML
pipelines
- Added test case in `tests/sql.yaml` to verify the
`calcite_connection_properties` option works correctly with PostgreSQL
functions like `INITCAP`
**Example Usage:**
```yaml
pipeline:
transforms:
- type: Create
name: CreateSampleData
config:
elements:
- {id: 1, tags: "java python go"}
- type: Sql
name: TransformWithPostgresFunction
input: CreateSampleData
config:
query: "SELECT id, STRING_TO_ARRAY(tags, ' ') as tag_list FROM
PCOLLECTION"
options:
calcite_connection_properties: {"fun": "postgresql"}
Fixes #36614
Test plan
- Added test case in tests/sql.yaml that uses INITCAP function with
calcite_connection_properties
- Verified YAML syntax is valid for both example and test files
- CI tests will verify the functionality
**Files changed:**
-
`sdks/python/apache_beam/yaml/examples/transforms/sql/sql_calcite_connection_properties.yaml`
(new)
- `sdks/python/apache_beam/yaml/tests/sql.yaml` (modified - added test
case)
