Schema:: ACCOUNT_USAGE

QUERY_ACCELERATION_ELIGIBLE view¶

This Account Usage view can be used to identify queries that are eligible for the query acceleration service (QAS).

Columns¶

Column Name	Data Type	Description
QUERY_ID	TEXT	Internal/system-generated identifier for the SQL statement.
QUERY_TEXT	TEXT	Text of the SQL statement.
START_TIME	TIMESTAMP_LTZ	Statement start time.
END_TIME	TIMESTAMP_LTZ	Statement end time.
WAREHOUSE_NAME	TEXT	Name of the warehouse that the query executed on.
WAREHOUSE_SIZE	TEXT	Size of the warehouse when this statement executed.
ELIGIBLE_QUERY_ACCELERATION_TIME	NUMBER	Amount of query execution time (in seconds) eligible for the query acceleration service.
UPPER_LIMIT_SCALE_FACTOR	NUMBER	Upper limit scale factor for the given query.
QUERY_HASH	TEXT	The hash value computed based on the canonicalized SQL text.
QUERY_HASH_VERSION	NUMBER	The version of the logic used to compute `QUERY_HASH`.
QUERY_PARAMETERIZED_HASH	TEXT	The hash value computed based on the parameterized query.
QUERY_PARAMETERIZED_HASH_VERSION	NUMBER	The version of the logic used to compute `QUERY_PARAMETERIZED_HASH`.

Usage notes¶

Latency for the view may be up to 180 minutes (three hours).

Query acceleration is supported for the following SQL commands:
- SELECT
- INSERT
- CREATE TABLE AS SELECT (CTAS)
For more information about query eligibility, see Eligible queries.
This view only includes eligible queries that have not been accelerated. If you have enabled the query acceleration service and previously QAS-eligible queries are now accelerated, they are not included in this view.

Examples¶

Identify the warehouses with the most queries eligible in a given period of time for the query acceleration service:

SELECT warehouse_name, COUNT(query_id) AS num_eligible_queries
  FROM SNOWFLAKE.ACCOUNT_USAGE.QUERY_ACCELERATION_ELIGIBLE
  WHERE start_time >= '2024-06-01 00:00'::TIMESTAMP
  AND end_time <= '2024-06-07 00:00'::TIMESTAMP
  GROUP BY warehouse_name
  ORDER BY num_eligible_queries DESC;
