在BigQuery中阅读Bigtable计数器

Question

我在Bigtable中有一个计数器表。在BigQuery中读取计数器数据的正确方法是什么？

当我使用BigQuery读取行时，所有单元格值在转换为Integer时显示为0。

SELECT integer (daily.column.cell.value) FROM rtda.counters

以下是使用hbase shell的示例输出：

hbase(main):019:0> get_counter 'counters','20110101','daily:clicks'

COUNTER VALUE = 8

我将列族编码设置为字节类型。 bq show rtda.counters输出：
