Amazon Redshift is a totally managed information warehousing service that gives each provisioned and serverless choices, making it extra environment friendly to run and scale analytics with out having to handle your information warehouse. Amazon Redshift lets you use SQL to research structured and semi-structured information throughout information warehouses, operational databases, and information lakes, utilizing AWS-designed {hardware} and machine studying (ML) to ship one of the best price-performance at scale.
On this put up, we present how Gameskraft used Amazon Redshift information sharing together with concurrency scaling and WLM optimization to help its rising analytics workloads.
Amazon Redshift use case
Gameskraft used Amazon Redshift RA3 cases with Redshift Managed Storage (RMS) for his or her information warehouse. The upstream information pipeline is a strong system that integrates numerous information sources, together with Amazon Kinesis and Amazon Managed Streaming for Apache Kafka (Amazon MSK) for dealing with clickstream occasions, Amazon Relational Database Service (Amazon RDS) for delta transactions, and Amazon DynamoDB for delta game-related info. Moreover, information is extracted from vendor APIs that features information associated to product, advertising and marketing, and buyer expertise. All of this numerous information is then consolidated into the Amazon Easy Storage Service (Amazon S3) information lake earlier than being uploaded to the Redshift information warehouse. These upstream information sources represent the info producer parts.
Gameskraft used Amazon Redshift workload administration (WLM) to handle priorities inside workloads, with greater precedence being assigned to the extract, rework, and cargo (ETL) queue that runs crucial jobs for information producers. The downstream shoppers include enterprise intelligence (BI) instruments, with a number of information science and information analytics groups having their very own WLM queues with applicable precedence values.
As Gameskraft’s portfolio of gaming merchandise elevated, it led to an approximate five-times progress of devoted information analytics and information science groups. Consequently, there was a fivefold rise in information integrations and a fivefold improve in advert hoc queries submitted to the Redshift cluster. These question patterns and concurrency have been unpredictable in nature. Additionally, over time the variety of BI dashboards (each scheduled and stay) elevated, which contributed to extra queries being submitted to the Redshift cluster.
With this rising workload, Gameskraft was observing the next challenges:
- Enhance in crucial ETL job runtime
- Enhance in question wait time in a number of queues
- Affect of unpredictable advert hoc question workloads throughout different queues within the cluster
Gameskraft was on the lookout for an answer that may assist them mitigate all these challenges, and supply flexibility to scale ingestion and consumption workload processing independently. Gameskraft was additionally on the lookout for an answer that may cater to their unpredictable future progress.
Answer overview
Gameskraft tackled these challenges in a phased method utilizing Amazon Redshift concurrency scaling, Amazon Redshift information sharing, Amazon Redshift Serverless, and Redshift provisioned clusters.
Amazon Redshift concurrency scaling allows you to simply help 1000’s of concurrent customers and concurrent queries, with persistently quick question efficiency. As concurrency will increase, Amazon Redshift routinely provides question processing energy in seconds to course of queries with none delays. When the workload demand subsides, this further processing energy is routinely eliminated, so that you pay just for the time when concurrency scaling clusters are in use. Amazon Redshift affords 1 hour of free concurrency scaling credit per lively cluster per day, permitting you to build up 30 hours of free credit monthly.
Gameskraft enabled concurrency scaling in selective WLM queues to ease the question wait time in these queues throughout peak utilization and likewise helped cut back ETL question runtime. Within the prior setup, we maintained 4 specialised queues for ETL, advert hoc queries, BI instruments, and information science. To forestall blockages for different processes, we imposed minimal question timeouts utilizing question monitoring guidelines (QMR). Nonetheless, each the ETL and BI instruments queues have been persistently occupied, impacting the efficiency of the remaining queues.
Concurrency scaling helped alleviate question wait time within the advert hoc question queue. Nonetheless, the problem of downstream consumption workloads (like advert hoc queries) impacting ingestion endured, and Gameskraft was on the lookout for an answer to handle these workloads independently.
The next desk summarizes the workload administration configuration previous to the answer implementation.

To realize flexibility in scaling, Gameskraft used Amazon Redshift information sharing. Amazon Redshift information sharing means that you can prolong the convenience of use, efficiency, and price advantages supplied by a single cluster to multi-cluster deployments whereas having the ability to share information. Knowledge sharing allows on the spot, granular, and quick information entry throughout Amazon Redshift information warehouses with out the necessity to copy or transfer it. Knowledge sharing offers stay entry to information in order that customers all the time observe probably the most up-to-date and constant info because it’s up to date within the information warehouse. You may securely share stay information throughout provisioned clusters, serverless endpoints inside AWS account, throughout AWS accounts, and throughout AWS Areas.
Knowledge sharing builds on Redshift Managed Storage (RMS), which underpins RA3 provisioned clusters and serverless workgroups, permitting a number of warehouses to question the identical information with separate remoted compute. Queries accessing shared information run on the buyer cluster and skim information from RMS straight with out impacting the efficiency of the producer cluster. Now you can quickly onboard workloads with numerous information entry patterns and SLA necessities and never be involved about useful resource competition.
We selected to run all ETL workloads within the main producer cluster to handle ETL independently. We used information sharing to share read-only entry to information with an information science serverless workgroup, a BI provisioned cluster, an advert hoc question provisioned cluster, and an information integration serverless workgroup. Groups utilizing these separate compute assets might then question the identical information with out copying the info between the producer and client. Moreover, we launched concurrency scaling to the buyer queues, prioritizing BI instruments, and prolonged the timeout for the remaining queues. These modifications notably enhanced total effectivity and throughput.

Answer implementation
Gameskraft is devoted to sustaining uninterrupted system operations, prioritizing seamless options over downtime. In pursuit of this precept, strategic measures have been undertaken to make sure a easy migration course of in direction of enabling information sharing, which included the next steps:
- Planning:
- Replicating customers and teams to the buyer, to mitigate potential entry issues for analytics, information science, and BI groups.
- Establishing a complete setup throughout the shoppers, encompassing important parts like exterior schemas for Amazon Redshift Spectrum.
- Advantageous-tuning WLM configurations tailor-made to the buyer’s necessities.
- Implementation:
- Introducing insightful monitoring dashboards in Grafana for CPU utilization, learn/write throughputs, IOPS, and latencies particular to the buyer cluster, enhancing oversight capabilities.
- Altering all interleaved key tables on the producer cluster to compound sortkey tables to seamlessly transition information.
- Creating an exterior schema from the info share database on the buyer, mirroring that of the producer cluster with an identical names. This method minimizes the necessity for making question changes in a number of areas.
- Testing:
- Conducting an inside week-long regression testing and auditing course of to meticulously validate all information factors by operating the identical workload and twice the workload.
- Remaining adjustments:
- Updating the DNS document for the cluster endpoint, which included changing the buyer cluster’s endpoint to the identical area because the producer cluster’s endpoint, to streamline connections and keep away from making adjustments in a number of locations.
- Making certain information safety and entry management by revoking group and consumer privileges from the producer cluster.

Key issues
Gameskraft embraces a contemporary information structure, with the info lake residing in Amazon S3. To grant seamless entry to the info lake, we use the progressive capabilities of Redshift Spectrum, which is a bridge between the info warehouse (Amazon Redshift) and information lake (Amazon S3). It means that you can carry out information transformations and evaluation straight on information saved in Amazon S3, with out having to duplicate the info into your Redshift cluster.
Gameskraft had a few key learnings whereas implementing this information sharing answer:
- First, as of this writing, Amazon Redshift information sharing doesn’t help including exterior schemas, tables, or late-binding views on exterior tables to the info share. To allow this, we now have created an exterior schema as a pointer to AWS Glue database. The identical AWS Glue database is referenced within the exterior schema on the buyer aspect.
- Second, Amazon Redshift doesn’t help sharing tables with interleaved kind keys and views that check with tables with interleaved kind keys. Because of the presence of interleaved kind keys throughout quite a few tables and views, a prerequisite for inclusion into the info share entails revising the kind key configuration to make use of compound kind key.
Conclusion
On this put up, we noticed how Gameskraft used information sharing and concurrency scaling in Amazon Redshift with a producer and client cluster structure to realize the next:
- Cut back question wait time for all queues within the producer and client
- Scale the producer and client independently based mostly on workload and queue necessities
- Enhance ETL pipeline efficiency and the info refresh cycle to help extra frequent refreshes within the producer cluster
- Onboard extra queues and workloads (BI instruments queue, information integration queue, information science queue, downstream crew’s queue, advert hoc question queue) within the client with out impacting the ETL pipeline within the producer cluster
- Flexibility to make use of a number of shoppers with a mixture of provisioned Redshift cluster and Redshift Serverless
These Amazon Redshift options and structure may help help a rising and unpredictable analytics workload.
