Google app engine 使用DatastoreIO将不同类型的实体保存到数据流中的数据存储中

我正在尝试使用DatastoreIO.v1（）.write（）将不同类型的实体写入数据存储

---

在我的转换函数中，UpsertStoreItemEntityFn扩展了dofn，感谢Abhishek；我们正在与数据存储客户团队联系，并对此进行调查。@Abhishek应该可以编写多种类型的数据，没有任何限制。您是否在日志中看到任何错误，或者只是数据不存在？您可以尝试将输出拆分为两个pcollection，然后使用不同的

数据存储。为每个pcollection编写
步骤：
  @Override
  public void processElement(ProcessContext processContext) throws Exception {
    IngestionJobRecord jobRecord = convertIntoIngestionJobRecord(processContext.element());

    String validRecordMsg = isRecordValid(jobRecord);
    if (validRecordMsg.isEmpty()) {
      processContext.output(makeSuccessRecordEntity(jobRecord));
    } else {
      processContext.output(makeErrorRecordEntity(validRecordMsg, jobRecord));
    }
  }


private Entity makeErrorRecordEntity(String errorMessage, IngestionJobRecord jobRecord) {
   Entity.Builder entityBuilder = Entity.newBuilder();

   // All created entities have the same ancestor Key.
   Key.Builder keyBuilder = makeKey("MyService.ErrorRecordEntity", UUID.randomUUID().toString());
   keyBuilder.getPartitionIdBuilder().setNamespaceId(tenantId);
   entityBuilder.setKey(keyBuilder.build());
   ..
   ..
}

private Entity makeSuccessRecordEntity(StoreItemEntity storeItemEntity) {
  Entity.Builder entityBuilder = Entity.newBuilder();

  // All created entities have the same ancestor Key.
  Key.Builder keyBuilder = makeKey("MyService.SuccessRecordEntity", UUID.randomUUID().toString());
  keyBuilder.getPartitionIdBuilder().setNamespaceId(tenantId);

  entityBuilder.setKey(keyBuilder.build());
  ..
  ..
}

.apply(DatastoreIO.v1().write().withProjectId("myProject"));
