Within the desk, hourly RPU consumption metrics for workgroup1 throughout completely different time intervals. The information reveals a reservation of 64 RPUs with no upfront cost possibility, which gives a 20% low cost. The desk breaks down the compute utilization into two classes: Reserved compute, constantly exhibiting 64 RPUs throughout all hours, and On-demand compute, which varies primarily based on precise consumption above the reserved capability. The underside row shows the Complete charged RPUs, which displays the ultimate billing after making use of the reserved occasion low cost. This helps visualize how the workload makes use of the reserved capability and any further on-demand utilization all through the desired time interval.The whole precise RPU consumption is 1,664 and the entire charged consumption is 1,484.8. This configuration leads to a ten.7% internet low cost.

Situation 2: A number of Redshift Serverless workgroups

On this situation, you’ve got a number of Redshift serverless workgroup in your setting and the workload is unfold as described within the following desk.

You should use the next question to search out the typical RPUs consumed in every hour in a workgroup.

SELECT
date_trunc('hour',end_time) AS run_hr,
avg(compute_capacity)
FROM SYS_SERVERLESS_USAGE
