Cloud Dataflow中的“侧面输入”是否支持从BigQuery视图读取？

Tried to point a side-input to a BigQuery view, instead of directly to a BigQuery table. It does not produce an error, but simply returns 0 rows. View works fine inside BigQuery.

试图将侧输入指向BigQuery视图，而不是直接指向BigQuery表。它不会产生错误，但只返回0行。 View在BigQuery中运行良好。

For example, given a view referencing a table 'types_test' with just 1 row:

例如，给定一个只引用1行的表'types_test'的视图：

In BigQuery, it works fine:

在BigQuery中，它工作正常：

But using the view as a side-input in Dataflow return 0 rows:

但是使用视图作为Dataflow中的side-input返回0行：

INFO: Reading from BigQuery table <removed>:CPT_7414_PLAYGROUND.view_test

INFO: Number of records read from BigQuery: 0

Do side-inputs support views in BigQuery, or do you need to do something else to use a view for a side-input?

在BigQuery中进行侧输入支持视图，还是需要做其他事情来使用视图进行侧输入？

Found in the FAQ's, that views are not currently supported.
