Aura from Unity (previously referred to as ironSource) is the market customary for creating wealthy gadget experiences that have interaction and retain clients. With a robust set of options, Aura allows full digital transformation, letting operators promote key providers exterior the shop, immediately on-device.
Amazon Redshift is a really helpful service for on-line analytical processing (OLAP) workloads akin to cloud information warehouses, information marts, and different analytical information shops. You need to use easy SQL to research structured and semi-structured information, operational databases, and information lakes to ship one of the best value/efficiency at any scale. The Amazon Redshift information sharing function offers immediate, granular, and high-performance entry with out information copies and information motion throughout a number of Redshift information warehouses in the identical or completely different AWS accounts and throughout AWS Areas. Information sharing offers dwell entry to information so that you simply all the time see essentially the most up-to-date and constant data because it’s up to date within the information warehouse.
Amazon Redshift Serverless makes it easy to run and scale analytics in seconds with out the necessity to arrange and handle information warehouse clusters. Redshift Serverless mechanically provisions and intelligently scales information warehouse capability to ship quick efficiency for even essentially the most demanding and unpredictable workloads, and also you pay just for what you utilize. You possibly can load your information and begin querying straight away within the Amazon Redshift Question Editor or in your favourite enterprise intelligence (BI) instrument and proceed to get pleasure from one of the best value/efficiency and acquainted SQL options in an easy-to-use, zero administration atmosphere.
On this put up, we describe Aura’s profitable and swift adoption of Redshift Serverless, which allowed them to optimize their general bidding commercial campaigns’ time to market from 24 hours to 2 hours. We discover why Aura selected this answer and what technological challenges it helped remedy.
Aura’s preliminary information pipeline
Aura is a pioneer in utilizing Redshift RA3 clusters with information sharing for extract, rework, and cargo (ETL) and BI workloads. Certainly one of Aura’s operations is bidding commercial campaigns. These campaigns are optimized by utilizing an AI-based bid course of that requires working tons of of analytical queries per marketing campaign. These queries are run on information that resides in an RA3 provisioned Redshift cluster.
The built-in pipeline is comprised of varied AWS providers:
The next diagram illustrates this structure.
Challenges of the preliminary structure
The queries for every marketing campaign run within the following method:
First, a preparation question filters and aggregates uncooked information, getting ready it for the following operation. That is adopted by the principle question, which carries out the logic in line with the preparation question end result set.
Because the variety of campaigns grew, Aura’s Information workforce was required to run tons of of concurrent queries for every of those steps. Aura’s present provisioned cluster was already closely utilized with information ingestion, ETL, and BI workloads, so that they have been on the lookout for cost-effective methods to isolate this workload with devoted compute sources.
The workforce evaluated a wide range of choices, together with unloading information to Amazon S3 and a multi-cluster structure utilizing information sharing and Redshift serverless. The workforce gravitated in direction of the multi-cluster structure with information sharing, because it requires no question rewrite, permits for devoted compute for this particular workload, avoids the necessity to duplicate or transfer information from the principle cluster, and offers excessive concurrency and computerized scaling. Lastly, it’s billed in a pay-for-what-you-use mannequin, and provisioning is easy and fast.
Proof of idea
After evaluating the choices, Aura’s Information workforce determined to conduct a proof of idea utilizing Redshift Serverless as a client of their fundamental Redshift provisioned cluster, sharing simply the related tables for working the required queries. Redshift Serverless measures information warehouse capability in Redshift Processing Models (RPUs). A single RPU offers 16 GB of reminiscence and a serverless endpoint can vary from 8 RPU to 512 RPU.
Aura’s Information workforce began the proof of idea utilizing a 256 RPU Redshift Serverless endpoint and progressively lowered the RPU to cut back prices whereas ensuring the question runtime was beneath the required goal.
Finally, the workforce determined to make use of a 128 RPU (2 TB RAM) Redshift Serverless endpoint as the bottom RPU, whereas utilizing the Redshift Serverless auto scaling function, which permits tons of of concurrent queries to run by mechanically upscaling the RPU as wanted.
Aura’s new answer with Redshift Serverless
After a profitable proof of idea, the manufacturing setup included including code to modify between the provisioned Redshift cluster and the Redshift Serverless endpoint. This was accomplished utilizing a configurable threshold based mostly on the variety of queries ready to be processed in a selected MSK subject consumed at the start of the pipeline. Small-scale marketing campaign queries would nonetheless run on the provisioned cluster, and large-scale queries would use the Redshift Serverless endpoint. The brand new answer makes use of an Amazon MWAA pipeline that fetches configuration data from a DynamoDB desk, consumes jobs that signify advert campaigns, after which runs tons of of EKS jobs triggered utilizing EKSPodOperator. Every job runs the 2 serial queries (the preparation question adopted by a fundamental question, which outputs the outcomes to Amazon S3). This occurs a number of hundred occasions concurrently utilizing Redshift Serverless compute sources.
Then the method initiates one other set of EKSPodOperator operators to run the AI coaching code based mostly on the info end result that was saved on Amazon S3.
The next diagram illustrates the answer structure.
Consequence
The general runtime of the pipeline was decreased from 24 hours to only 2 hours, a 12-times enchancment. This integration of Redshift Serverless, coupled with information sharing, led to a 90% discount in pipeline period, negating the need for information duplication or question rewriting. Furthermore, the introduction of a devoted client as an unique compute useful resource considerably eased the load of the producer cluster, enabling working small-scale queries even sooner.
“Redshift Serverless and information sharing enabled us to provision and scale our information warehouse capability to ship quick efficiency, excessive concurrency and deal with difficult ML workloads with very minimal effort.”

Learnings
Aura’s Information workforce is very targeted on working in an economical method and has due to this fact applied a number of price controls of their Redshift Serverless endpoint:
- Restrict the general spend by setting a most RPU-hour utilization restrict (per day, week, month) for the workgroup. Aura configured that restrict so when it’s reached, Amazon Redshift will ship an alert to the related Amazon Redshift administrator workforce. This function additionally permits writing an entry to a system desk and even turning off consumer queries.
- Use a most RPU configuration, which defines the higher restrict of compute sources that Redshift Serverless can use at any given time. When the utmost RPU restrict is about for the workgroup, Redshift Serverless scales inside that restrict to proceed to run the workload.
- Implement question monitoring guidelines that stop wasteful useful resource utilization and runaway prices attributable to poorly written queries.
