Which language do you use to query an eventhouse?
Why B is the answer
KQL
KQL is the query language for eventhouses.
In detail
- An eventhouse uses KQL.
- A KQL query reads as a pipeline of steps.
Use case
An illustrative scenario, not a real incident.
An engineer asks for error counts per minute over the last hour, and a short KQL query returns them.
