Re: Loosing records when using BigQuery IO Connector
Hi,
I tested with streaming insert and file load, and they all worked as
expected. But looks like storage API is the new way to go so want to test
it too. I am using Apache Beam v2.46.0 and running it with Google Dataflow.
Thanks

Re: Loosing records when using BigQuery IO Connector
What version of Beam are you using? There are no known data-loss bugs in
the connector, however if there has been a regression we would like to
address it with high priority.

Re: Loosing records when using BigQuery IO Connector
Does FILE_LOADS (
https://beam.apache.org/releases/javadoc/2.46.0/org/apache/beam/sdk/io/gcp/bigquery/BigQueryIO.Write.Method.html#FILE_LOADS)
work for your case?
For STORAGE_WRITE_API, it has been actively improved. If the latest SDK
still has this issue, I highly recommend you to create a Google Cloud
support ticket.

Loosing records when using BigQuery IO Connector
Hi,
I have a job that uses BigQuery IO Connector to write to a BigQuery table.
When I test it with a small number of records (100) it works as expected
but when I tested it with a larger number of records (1), I don’t see
all of the records written to the output table but only part of it. It
changes from run to run but no more than 1000 records as I have seen so far.
There are WARNING log entries in the job log like this
by client #0 failed with error, operations will be retried.
com.google.cloud.bigquery.storage.v1.Exceptions$OffsetAlreadyExists:
ALREADY_EXISTS: The offset is within stream, expected offset 933,
received 0
And one log entry like this
Finalize of stream [stream-name] finished with row_count: 683
If I sum all the numbers reported in the WARNING message with the one in
the finalize of stream above, I get 1, which is exactly the number of
input records.
My pipeline uses 1 worker and it looks like this
WriteResult writeResult = inputCollection.apply(
"Save Events To BigQuery",
BigQueryIO.write()
.to(options.getTable())
.withFormatFunction(TableRowMappers::toRow)
.withMethod(Method.STORAGE_WRITE_API)
.withCreateDisposition(BigQueryIO.Write.CreateDisposition.CREATE_NEVER)
.withWriteDisposition(BigQueryIO.Write.WriteDisposition.WRITE_APPEND)
.withExtendedErrorInfo());
writeResult
.getFailedStorageApiInserts()
.apply("Log failed inserts", ParDo.of(new PrintFn<>()));
There are no log entries for the failed inserts.
Is there anything wrong with my pipeline code or is it a bug in BigQuery IO
Connector?
Thanks
-Binh
