damccorm opened a new issue, #21321:
URL: https://github.com/apache/beam/issues/21321
In the following code snippet the data gets successfully inserted into
BigQuery. But the "getSuccessfulInserts" Transform never returns any data. No
log is written.
```
WriteResult writeResultCategory =
categoryWithHeader
.apply("BQ Insert
Category",
BigQueryIO.<CategoryWithHeader>write()
.withCreateDisposition(CreateDisposition.CREATE_IF_NEEDED)
.withWriteDisposition(WriteDisposition.WRITE_APPEND)
.withMethod(BigQueryIO.Write.Method.STREAMING_INSERTS)
.withExtendedErrorInfo()
.withFailedInsertRetryPolicy(InsertRetryPolicy.neverRetry())
.useBeamSchema()
.to(getTableReference(tableCategory))
);
writeResultCategory
.getSuccessfulInserts()
.apply("Log
successful inserts", ParDo.of(new DoFn<TableRow, Void>() {
@ProcessElement
public void process(ProcessContext c) {
LOG.info("Successfully inserted
Category: " + c.element());
}
}));
```
The problematic code might be in
```
org.apache.beam.sdk.io.gcp.bigquery.BatchedStreamingWrite.BatchAndInsertElements#finishBundle
```
The successfulInserts are never emitted from here.
Please compare this behaviour with the following method where the
successfulInserts are emitted:
```
org.apache.beam.sdk.io.gcp.bigquery.BatchedStreamingWrite.InsertBatchedElements#processElement
```
