BigQuery: data is sometimes not inserted in tables

[z0mg]

Hi,

I'm having random data missing/not showing up in BigQuery issues. I would seemingly write data without issues, but SELECT * would return nothing.

1. Have tried latest version but still same issue.

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-bigquery</artifactId>
  <version>2.28.0</version> 
</dependency>

2. Linux and Windows
3. JDK 8.202

Steps to reproduce

Issue is random, can't reproduce reliably. The writes are batched to 1-2k rows and 99% they work.

The control panel shows no errors. None of the quotas show up as exceeded. I get no exceptions and response.getInsertErrors() is always null. The issue seems to happen when doing intensive writes, as less batches per minute of the same size work fine.

Any ideas what's wrong? thank you.

Code example

GoogleCredential credential = new GoogleCredential.Builder().setTransport(new NetHttpTransport())
    .setJsonFactory(new JacksonFactory())
    .setClientSecrets("clientId", "clientSecret")
    .build()
    .setFromTokenResponse(new TokenResponse().setRefreshToken("refreshToken");

Bigquery bigquery = new Bigquery.Builder(new NetHttpTransport(), new JacksonFactory(), credential)
    .setApplicationName("name").build();

List<TableDataInsertAllRequest.Rows> rowList = new ArrayList<TableDataInsertAllRequest.Rows>();

TableRow rowWrapper = new TableRow();
rowWrapper.set("date", item.GetDate());
rowWrapper.set("value", item.GetValue());

TableDataInsertAllRequest.Rows insertRowRequest = new TableDataInsertAllRequest.Rows();

rowList.add(insertRowRequest);

TableDataInsertAllRequest content = new TableDataInsertAllRequest().setRows(rowList);

InsertAll op = bigquery.tabledata().insertAll("project", "dataset", "table", content);
    
TableDataInsertAllResponse response = op.execute();
if (response.getInsertErrors() == null)
{
  ; // all good
}
