Syntax

DESCRIBE QUERY METRICS [query_id | query_name[:query_version]]
[WITH (query_metrics_parameter = value [, ...])];

Description

This command provides a snapshot of metrics for a . The 4 metrics shown are:

  1. NumRecordsInPerSecond

  2. NumRecordsOutPerSecond

  3. NumBytesInPerSecond

  4. NumBytesOutPerSecond.

Returned metrics represent a snapshot of the value of each metric at the time this command was run.

Note Metrics may not always be available for queries. In this case, stats are replaced with n/a or with a 02000 SQL error code. The example below displays a query in a terminal state.

See on how streaming queries operate in DeltaStream.

The query is visible only if the current role has USAGE privileges.

Arguments

query_id

query_name

query_version

WITH (query_metrics_parameter = value [, ...])

Optionally, this clause specifies Query Metrics Parameters.

Describe metrics for a query in the STOPPED state

The following example show that when a query is in a terminated state — in this case, STOPPED — the system returns a SQL code of 02000 instead:

demodb.public/demostore# DESCRIBE QUERY METRICS 4f5f6a0f-1f71-40ec-902a-0ec821bc36f3 WITH ('from' = LAST 3 HOURS, FOR METRICS (numRecordsInPerSecond));
sql error: no data found (SQLState: 02000) (request ID: ...)

This is the unique identifier of the query to describe. See to find out how to list all queries to which the user has access. The first column (ID) in the response corresponds with the query_id.

This is the name of the query to describe. See to find out how to list all queries to which the user has access. The column (Name) in the response corresponds with the query_name. The query_version property disambiguates between multiple queries with the same name.

This is the version of the query to describe. See to find out how to list all queries to which the user has access. The column (Version) in the response corresponds with the query_version. If query_name is provided without a query_version, the latest query_version is used.

The following describes a simple query with a source relation, users_log, filtering on a userid column and writing the results into a Changelog sink relation, users2468_log:

The following describes a JOIN query that joins a , pageviews, and a relation, users_log, on a userid column and writes the resulting records into a pv_user2468_interest Changelog relation:
