Amazon Redshift Serverless mechanically scales compute capability to match workload calls for, measuring this capability in Redshift Processing Items (RPUs). Though conventional scaling primarily responds to question queue instances, the brand new AI-driven scaling and optimization characteristic affords a extra refined method by contemplating a number of elements together with question complexity and information quantity. Clever scaling addresses key information warehouse challenges by stopping each over-provisioning of sources for efficiency and under-provisioning to save lots of prices, significantly for workloads that fluctuate based mostly on every day patterns or month-to-month cycles.
Amazon Redshift serverless now affords enhanced flexibility in configuring workgroups by two major strategies. Customers can both set a base capability, specifying the baseline RPUs for question execution, with choices starting from 8 to 1024 RPUs and every RPU offering 16 GB of reminiscence, or they will go for the price-performance goal. Amazon Redshift Serverless AI-driven scaling and optimization can adapt extra exactly to numerous workload necessities and employs clever useful resource administration, mechanically adjusting sources throughout question execution for optimum efficiency. Think about using AI-driven scaling and optimization in case your present workload requires 32 to 512 base RPUs. We don’t suggest utilizing this characteristic for lower than 32 base RPU or greater than 512 base RPU workloads.
On this put up, we reveal how Amazon Redshift Serverless AI-driven scaling and optimization impacts efficiency and value throughout completely different optimization profiles.
Choices in AI-driven scaling and optimization
Amazon Redshift Serverless AI-driven scaling and optimization affords an intuitive slider interface, letting you stability value and efficiency objectives. You’ll be able to choose from 5 optimization profiles, starting from Optimized for Price to Optimized for Efficiency, as proven within the following diagram. Your slider place determines how Amazon Redshift allocates sources and implements AI-driven scaling and optimizations, to attain your required price-performance goal.
The slider affords the next choices:
Optimized for Price (1)
Prioritizes price financial savings over efficiency
Allocates minimal sources in favor of saving on prices
Finest for workloads the place efficiency isn’t time-critical
Price-Balanced (25)
Balances in the direction of price financial savings whereas sustaining affordable efficiency
Allocates reasonable sources
Appropriate for combined workloads with some flexibility in question time
Balanced (50)
Supplies equal emphasis on price effectivity and efficiency
Allocates optimum sources for many use circumstances
Splendid for general-purpose workloads
Efficiency-Balanced (75)
Favors efficiency whereas sustaining some price management
Allocates further sources when wanted
Appropriate for workloads requiring constantly quick question elapsed time
Optimized for Efficiency (100)

Which workloads to contemplate for AI-driven scaling and optimizations
The Amazon Redshift Serverless AI-driven scaling and optimization capabilities may be utilized to virtually each analytical workload. Amazon Redshift will assess and apply optimizations in response to your price-performance goal—price, stability, or efficiency.
Most analytical workloads function on tens of millions and even billions of rows and generate aggregations and complicated calculations. These workloads have excessive variability for question patterns and variety of queries. The Amazon Redshift Serverless AI-driven scaling and optimization will enhance the value, efficiency, or each as a result of it learns the patterns (the repeatability of your workload) and can allocate extra sources in the direction of efficiency enhancements when you’re performance-focused or fewer sources when you’re cost-focused.
Price-effectiveness of AI-driven scaling and optimization
To successfully decide the effectiveness of Amazon Redshift Serverless AI-driven scaling and optimization we’d like to have the ability to measure your present state of price-performance. We encourage you to measure your present price-performance by utilizing sys_query_history to calculate the entire elapsed time of your workload and notice the beginning time and finish time. Then use sys_serverless_usage to calculate the associated fee. You need to use the question from the Amazon Redshift documentation and add the identical begin and finish instances. This can set up your present value efficiency, and now you’ve got a baseline to check towards.
If such measurement isn’t sensible as a result of your workloads are constantly working and it’s impractical so that you can decide a hard and fast begin and finish time, then one other manner is to check holistically, examine your month over month price, examine your person sentiment in the direction of efficiency, in the direction of system stability, enhancements in information supply, or discount in general month-to-month processing instances.
Benchmark carried out and outcomes
We evaluated the optimization choices utilizing the TPCDS 3TB dataset from the AWS Labs GitHub repository (amazon-redshift-utils). We deployed this dataset throughout three Amazon Redshift Serverless workgroups configured as Optimized for Price, Balanced, and Optimized for Efficiency. To create a practical reporting atmosphere, we configured three Amazon Elastic Compute Cloud (Amazon EC2) cases with JMeter (one per endpoint) and ran 15 chosen TPCDS queries concurrently for roughly 1 hour, as proven within the following screenshot.
We disabled the consequence cache to verify Amazon Redshift Serverless ran all queries instantly, offering correct measurements. This setup helped us seize genuine efficiency traits throughout every optimization profile. Additionally, we designed our take a look at atmosphere with out setting the Amazon Redshift Serverless workgroup max capability parameter—a key configuration that controls the utmost RPUs obtainable to your information warehouse. By eradicating this restrict, we may clearly showcase how completely different configurations have an effect on scaling habits in our take a look at endpoints.
Our complete take a look at plan included working every of the 15 queries 355 instances, producing 5,325 queries per take a look at cycle. The AI-driven scaling and optimization wants a number of iterations to determine patterns and optimize RPUs, so we ran this workload 10 instances. By means of these repetitions, the AI realized and tailored its habits, processing a complete of 53,250 queries all through our testing interval.
The testing revealed how the AI-driven scaling and optimization system adapts and optimizes efficiency throughout three distinct configuration profiles: Optimized for Price, Balanced, and Optimized for Efficiency.
Queries and elapsed time
Though we ran the identical core workload repeatedly, we used variable parameters in JMeter to generate completely different values for the WHERE clause circumstances. This method created comparable however not similar workloads, introducing pure variations that confirmed how the system handles real-world situations with various question patterns.
Our elapsed time evaluation demonstrates how every configuration achieved its efficiency targets, as proven by the typical consumption metrics for every endpoint, as proven within the following screenshot.
