How to set wait timeout for a queue in Amazon redshift?


How to set wait timeout for a queue in Amazon redshift?

around this issue You can control the amount of time that query spends waiting in queue indirectly by specifying statement_timeout configuration parameter on session or whole cluster level in addition to max_execution_time parameter on WLM level. If both WLM timeout (max_execution_time) and statement_timeout are specified, the shorter timeout is used. In this case the maximum time that query will be able to wait in the queue is "statement_timeout" minus "max_execution_time".

it helps some times Assuming you have the ODBC driver installed already, you should be able to use an alteration of this string:
code :
Driver={Amazon Redshift (x64)}; 
Server=examplecluster.abc123xyz789.us-west-2.redshift.amazonaws.com; 
Database=dev; UID=masteruser; PWD=your_password; Port=5439

may help you . The following query will list top queries by execution time, but as John mentions above, will only return two to five days of log history.
code :
SELECT
w.userid,
w.query,
w.service_class_start_time AS "Day",
w.total_queue_time / 60000000 AS "Total Queue Time Minutes",
w.total_exec_time / 60000000 AS "Total Exec Time Minutes",
w.total_queue_time / 60000000 + w.total_exec_time / 60000000 AS "Total Time  Minutes"
FROM
stl_wlm_query w
ORDER BY
6 DESC
