ggjh-159 opened a new pull request, #12666:
URL: https://github.com/apache/gluten/pull/12666
issue: #12665
## What changes are proposed in this pull request?
Adds Substrait conversion and unit tests for a batch of stateless scalar
expressions in the gluten-flink planner, so common Flink SQL
string/time/control scalar functions can run on the velox backend.
### Planner
- `RexNodeConverter.java`: handles TIMESTAMP literal conversion to
`TimestampValue.create(epochSeconds, nanos)`.
- `RexCallConverterFactory.java`: adds new mappings:
- Time fields: `YEAR` / `MONTH` / `DAYOFMONTH` / `DAYOFYEAR` / `DAYOFWEEK`
/ `QUARTER` / `HOUR` / `MINUTE` / `SECOND` / `WEEK`.
- String/control: `SUBSTRING` / `COALESCE` / `FROM_BASE64` / `JSON_VALUE`
(mapped to the velox `get_json_object`).
## How was this patch tested?
- `ScalarFunctionsTest.java`: new test cases covering the mappings above:
- `testQuarterAndWeekFromTimestamp` (QUARTER + WEEK)
- `testHourFromTimestamp` (HOUR)
- `testMinuteSecondFromTimestamp` (MINUTE + SECOND)
- `testDayFieldsFromTimestamp` (DAYOFMONTH + DAYOFWEEK + DAYOFYEAR,
including the Sunday boundary)
- `testSubstring` / `testCoalesce` / `testFromBase64` / `testJsonValue`
