Cross-tenant query federation

Note

You need to enable multitenancy_enabled: true in the cluster for multi-tenant querying to work. Refer to Enable multi-tenancy for more details and implications of multitenancy_enabled: true.

Tempo supports multi-tenant queries for search, search-tags, and trace-by-ID search operations.

To perform multi-tenant queries, send tenant IDs separated by a | character in the X-Scope-OrgID header, for example, foo|bar.

By default, cross-tenant query is enabled and can be controlled using multi_tenant_queries_enabled configuration setting.

YAML 
query_frontend:
   multi_tenant_queries_enabled: true

For more information on configuration options, refer to Enable multitenancy.

TraceQL queries

Queries performed using the cross-tenant configured data source, in either Explore or inside of dashboards, are performed across all the tenants that you specified in the X-Scope-OrgID header.

TraceQL queries that compare multiple spansets may not correctly return all traces in a cross-tenant query. For instance,

{ span.attr1 = "bar" } && { span.attr2 = "foo" }

TraceQL evaluates a contiguously stored trace. If these two conditions are satisfied in separate tenants, then Tempo doesn’t correctly return the trace.
