Starts query sampling on one namespace of the specified cluster. Sampled queries feed the shard key analysis for the namespace. The response reports the observed sampling state, in which active may still be false: the cluster applies the sampling configuration asynchronously.

- Project Data Access Read Only
- Project Data Access Read Write
- Project Stream Processing Owner
Path parameters
-
Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.
NOTE: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.
Format should match the following pattern:
^([a-f0-9]{24})$. -
Human-readable label that identifies the cluster.
Format should match the following pattern:
^[a-zA-Z0-9][a-zA-Z0-9-]*$.
Query parameters
-
Flag that indicates whether Application wraps the response in an
envelopeJSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.Default value is
false. -
Flag that indicates whether the response body should be in the prettyprint format.
Default value is
false.Prettyprint
