Final yr at re:Invent, we launched the preview of Amazon Redshift Serverless, a serverless choice of Amazon Redshift that permits you to analyze knowledge at any scale with out having to handle knowledge warehouse infrastructure. You simply must load and question your knowledge, and also you pay just for what you utilize. This permits extra firms to construct a contemporary knowledge technique, particularly to be used circumstances the place analytics workloads usually are not working 24-7 and the info warehouse just isn’t energetic on a regular basis. Additionally it is relevant to firms the place using knowledge expands inside the group and customers in new departments need to run analytics with out having to take possession of knowledge warehouse infrastructure.
At present, I’m pleased to share that Amazon Redshift Serverless is typically out there and that we added many new capabilities. We’re additionally decreasing Amazon Redshift Serverless compute prices in comparison with the preview.
Now you can create a number of serverless endpoints per AWS account and Area utilizing namespaces and workgroups:
- A namespace is a set of database objects and customers, reminiscent of database identify and password, permissions, and encryption configuration. That is the place your knowledge is managed and the place you possibly can see how a lot storage is used.
- A workgroup is a set of compute sources, together with community and safety settings. Every workgroup has a serverless endpoint to which you’ll be able to join your functions. When configuring a workgroup, you possibly can arrange personal or publicly accessible endpoints.
Every namespace can have just one workgroup related to it. Conversely, every workgroup will be related to just one namespace. You may have a namespace with none workgroup related to it, for instance, to make use of it just for sharing knowledge with different namespaces in the identical or one other AWS account or Area.
In your workgroup configuration, now you can use question monitoring guidelines to assist hold your prices beneath management. Additionally, the way in which Amazon Redshift Serverless mechanically scales knowledge warehouse capability is extra clever to ship quick efficiency for demanding and unpredictable workloads.
Let’s see how this works with a fast demo. Then, I’ll present you what you are able to do with namespaces and workgroups.
Utilizing Amazon Redshift Serverless
Within the Amazon Redshift console, I choose Redshift serverless within the navigation pane. To get began, I select Use default settings to configure a namespace and a workgroup with the commonest choices. For instance, I’ll have the ability to join utilizing my default VPC and default safety group.
With the default settings, the one choice left to configure is Permissions. Right here, I can specify how Amazon Redshift can work together with different companies reminiscent of S3, Amazon CloudWatch Logs, Amazon SageMaker, and AWS Glue. To load knowledge later, I give Amazon Redshift entry to an S3 bucket. I select Handle IAM roles after which Create IAM position.
When creating the IAM position, I choose the choice to present entry to particular S3 buckets and decide an S3 bucket in the identical AWS Area. Then, I select Create IAM position as default to finish the creation of the position and to mechanically use it because the default position for the namespace.
I select Save configuration and after a couple of minutes the database is prepared to be used. Within the Serverless dashboard, I select Question knowledge to open the Redshift question editor v2. There, I observe the directions within the Amazon Redshift Database Developer information to load a pattern database. If you wish to do a fast check, just a few pattern databases (together with the one I’m utilizing right here) are already out there within the sample_data_dev database. Word additionally that loading knowledge into Amazon Redshift just isn’t required for working queries. I can use knowledge from an S3 knowledge lake in my queries by creating an exterior schema and an exterior desk.
The pattern database consists of seven tables and tracks gross sales exercise for a fictional “TICKIT” web site, the place customers purchase and promote tickets for sporting occasions, exhibits, and live shows.
To configure the database schema, I run just a few SQL instructions to create the customers, venue, class, date, occasion, itemizing, and gross sales tables.
Then, I obtain the tickitdb.zip file that comprises the pattern knowledge for the database tables. I unzip and cargo the information to a tickit folder in the identical S3 bucket I used when configuring the IAM position.
Now, I can use the COPY command to load the info from the S3 bucket into my database. For instance, to load knowledge into the customers desk:
copy customers from 's3://MYBUCKET/tickit/allusers_pipe.txt' iam_role default;
The file containing the info for the gross sales desk makes use of tab-separated values:
copy gross sales from 's3://MYBUCKET/tickit/sales_tab.txt' iam_role default delimiter 't' timeformat 'MM/DD/YYYY HH:MI:SS';After I load knowledge in all tables, I begin working some queries. For instance, the next question joins 5 tables to search out the highest 5 sellers for occasions primarily based in California (observe that the pattern knowledge is for the yr 2008):
choose sellerid, username, (firstname ||' '|| lastname) as sellername, venuestate, sum(qtysold)
from gross sales, date, customers, occasion, venue
the place gross sales.sellerid = customers.userid
and gross sales.dateid = date.dateid
and gross sales.eventid = occasion.eventid
and occasion.venueid = venue.venueid
and yr = 2008
and venuestate="CA"
group by sellerid, username, sellername, venuestate
order by 5 desc
restrict 5;
Now that my database is prepared, let’s see what I can do by configuring Amazon Redshift Serverless namespaces and workgroups.
Utilizing and Configuring Namespaces
Namespaces are collections of database knowledge and their safety configurations. Within the navigation pane of the Amazon Redshift console, I select Namespace configuration. Within the checklist, I select the default namespace that I simply created.
Within the Information backup tab, I can create or restore a snapshot or restore knowledge from one of many restoration factors which are mechanically created each half-hour and stored for twenty-four hours. That may be helpful to get well knowledge in case of unintentional writes or deletes.
Within the Safety and encryption tab, I can replace permissions and encryption settings, together with the AWS Key Administration Service (AWS KMS) key used to encrypt and decrypt my sources. On this tab, I may also allow audit logging and export the consumer, connection, and consumer exercise logs to CloudWatch Logs.
Within the Datashares tab, I can create a datashare to share knowledge with different namespaces and AWS accounts in the identical or completely different Areas. On this tab, I may also create a database from a share I obtain from different namespaces or AWS accounts, and I can see the subscriptions for datashares managed by AWS Information Alternate.
Once I create a datashare, I can choose which objects to incorporate. For instance, right here I need to share solely the date and occasion tables as a result of they don’t include delicate knowledge.
Utilizing and Configuring Workgroups
Workgroups are collections of compute sources and their community and safety settings. They supply the serverless endpoint for the namespace they’re configured for. Within the navigation pane of the Amazon Redshift console, I select Workgroup configuration. Within the checklist, I select the default namespace that I simply created.
Within the Information entry tab, I can replace the community and safety settings (for instance, change the VPC, the subnets, or the safety group) or make the endpoint publicly accessible. On this tab, I may also allow Enhanced VPC routing to route community visitors between my serverless database and the info repositories I take advantage of (for instance, the S3 buckets used to load or unload knowledge) via a VPC as an alternative of the web. To entry serverless endpoints which are in one other VPC or subnet, I can create a VPC endpoint managed by Amazon Redshift.
Within the Limits tab, I can configure the bottom capability (expressed in Redshift processing models, or RPUs) used to course of my queries. Amazon Redshift Serverless scales the capability to take care of a better variety of customers. Right here I even have the choice to extend the bottom capability to hurry up my queries or lower it to cut back prices.
On this tab, I may also set Utilization limits to configure each day, weekly, and month-to-month thresholds to maintain my prices predictable. For instance, I configured a each day restrict of 200 RPU-hours, and a month-to-month restrict of two,000 RPU-hours for my compute sources. To manage the data-transfer prices for cross-Area datashares, I configured a each day restrict of three TB and a weekly restrict of 10 TB. Lastly, to restrict the sources utilized by every question, I take advantage of Question limits to outing queries working for greater than 60 seconds.
Availability and Pricing

Virginia), US West (Oregon), Europe (Frankfurt), Europe (Eire), Europe (London), Europe (Stockholm), and Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), and Asia Pacific (Tokyo) AWS Areas.
You may hook up with a workgroup endpoint utilizing your favourite consumer instruments by way of JDBC/ODBC or with the Amazon Redshift question editor v2, a web-based SQL consumer utility out there on the Amazon Redshift console. When utilizing internet services-based functions (reminiscent of AWS Lambda features or Amazon SageMaker notebooks), you possibly can entry your database and carry out queries utilizing the built-in Amazon Redshift Information API.
With Amazon Redshift Serverless, you pay just for the compute capability your database consumes when energetic. The compute capability scales up or down mechanically primarily based in your workload and shuts down in periods of inactivity to save lots of time and prices.
