> ---------------------------------------------------------------
>
> Key: BEAM-8029
> URL: https://issues.apache.org/jira/browse/BEAM-8029
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.14.0
> Reporter: Chris Larsen
> Assignee: Svetak Vihaan Sundhar
> Priority: P3
> Labels: stale-assigned

> Code to read from BigQuery that is causing the issue:
> {code:java}
> pipeline
> .apply(BigQueryIO
> .read(SchemaAndRecord::getRecord)
> .from(options.getTableRef())
> .withMethod(Method.DIRECT_READ)
> .withCoder(AvroCoder.of(schema)))
> {code}
> If we remove .withMethod(Method.DIRECT_READ) then there is no issue.
>
> The error is:
> {code:java}
> org.apache.beam.sdk.util.IllegalMutationException: PTransform BigQueryIO.TypedRead/Read(BigQueryStorageTableSource) mutated value {"device_id": "rpi-rpi0-thermostat", "temperature_c": 20.0, "temperature_f": 52.0, "sample_time": 1564412307969368, "humidity": 74.3} after it was output (new value was {"device_id": "rpi-rpi0-thermostat", "temperature_c": 20.0, "temperature_f": 52.0, "sample_time": 1564412360458615, "humidity": 74.7}).
