[GitHub] [beam] bvolpato opened a new issue, #25319: [Bug]: BigQueryStorageAvroReader illegal value mutation

bvolpato opened a new issue, #25319:
URL: https://github.com/apache/beam/issues/25319

   ### What happened?
   
   When using `BigQueryIO` with `BigQueryStorageAvroReader` (see [BigQueryToParquet](https://github.com/GoogleCloudPlatform/DataflowTemplates/blob/main/v2/bigquery-to-parquet/src/main/java/com/google/cloud/teleport/v2/templates/BigQueryToParquet.java) template), MutationDetectors fail with the exception:
   
   ```
   Caused by: org.apache.beam.sdk.util.IllegalMutationException: PTransform ReadFromBigQuery/Read(BigQueryStorageTableSource) mutated value {"test_id": 2, "dxBa5HJ2L1": "lRc0"} after it was output (new value was {"test_id": 4, "dxBa5HJ2L1": "TDz"}). Values must not be mutated in any way after being output.

   While DataflowRunner apparently runs without issues, this operation might be risky / non-deterministic.
