BigQuery 在其他区域之间有区域限制或延迟吗? [英] BigQuery has region restriction or delay between other regions?

问题描述

我想将数据从 GCE 实例存储在 BigQuery 上，并从不同的区域实例查询.
例如)存储来自欧盟实例的数据，来自美国实例的查询.

这可以毫不拖延吗?
我认为将数据复制到其他地区需要一些时间.

解决方案

BigQuery 有区域限制...?

很少，如下图

1. 您不能在欧盟和美国地区之间复制表格.你会得到类似下面的内容
   无法在不同位置读写:来源:美国，目的地:欧盟

2. 此外，您不能在同一查询中查询美国和欧盟的数据.你会得到类似下面的内容
   无法跨位置处理数据:欧盟、美国

<块引用>

我认为将数据复制到其他地区需要一些时间.

查询时没有任何复制.您只需查询该区域/在该区域中的数据(当然，如果您可以访问)

<块引用>

这可以毫不拖延吗?

因此没有与复制相关的延迟，因为没有复制！！

I want to store data on BigQuery from GCE instance, and query to it from different region instance.
e.g.)store data from EU instance, query from US instance.

Is this possible without any delay?
I think it would take some times to replicate data to other region.

解决方案

BigQuery has region restriction ...?

There are few, like below

1. You cannot copy tables between EU and US regions. You will get something like below
   Cannot read and write in different locations: source: US, destination: EU

2. Also you cannot query data in US and EU within the same query. You will get something like below
   Cannot process data across locations: EU,US

I think it would take some times to replicate data to other region.

There is no any replication when you do query. You just query data where it is / in that region (if you have access of course)

Is this possible without any delay?

Thus no delay related to replication, as there is no replication!!
