Kusto Go API 从多个表查询

Question content

I am using Kusto API to query the logs in 2 tables, but they are in 2 different databases, which are located in different in a cluster and therefore have different endpoints (I cannot modify the cluster). I want to know if it is possible to query logs from two tables using Kusto API

Correct answer

No matter which client library/tool you use, as long as you have The databases all have read permissions, so you can include references to databases in different clusters in the query text.

The cluster you select to run the query will run the subquery against the second cluster.
Please refer to: Cross-cluster and cross-database query

For example, run the following query against database database1 on cluster cluster1.westus:

union withsource = T
   Table1, // this is in 'database1' in 'cluster1.westus'
   cluster("cluster2.westus2").database("database2").Table2,
   cluster("cluster2.centralus").database("database3").Table3
| where Timestamp > ago(1h)
| summarize count() by T
