walterddr opened a new pull request #7485:
URL: https://github.com/apache/pinot/pull/7485
Currently if there's a double quoted PQL syntax ingestion transform such as
```
"ingestionConfig": {
"transformConfigs": [
{
"columnName": "created_at_timestamp",
"transformFunction": "fromDateTime(created_at,
\"yyyy-MM-dd''T''HH:mm:ss''Z''\")"
}
]
},
```
It will fail because the double quoted literal is considered as quoted
identifier in Calcite SQL parser.
This is not a problem during SQL execution because the column will not be
found. but during ingestion we dont have a proper schema validation thus
exception will not be meaningful.
Propose to wrap exception in InbuiltFunctionEvaluator that executes any
ScalarFuntion in FunctionRegistry and provide extra context information about
the argument that passed in.
