Amazon Redshift Serverless – Now Typically Out there with New Capabilities


Final yr at re:Invent, we launched the preview of Amazon Redshift Serverless, a serverless possibility of Amazon Redshift that allows you to analyze knowledge at any scale with out having to handle knowledge warehouse infrastructure. You simply have to load and question your knowledge, and also you pay just for what you employ. This permits extra corporations 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 shouldn’t be lively on a regular basis. Additionally it is relevant to corporations the place the usage of knowledge expands throughout the group and customers in new departments wish to run analytics with out having to take possession of knowledge warehouse infrastructure.

Immediately, I’m pleased to share that Amazon Redshift Serverless is typically out there and that we added many new capabilities. We’re additionally lowering 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, comparable to 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 assets, together with community and safety settings. Every workgroup has a serverless endpoint to which you’ll 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 might be related to just one namespace. You’ll be able to 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 maintain your prices below management. Additionally, the best way Amazon Redshift Serverless robotically 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 possibility left to configure is Permissions. Right here, I can specify how Amazon Redshift can work together with different providers comparable to 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 function.

Console screenshot.

When creating the IAM function, I choose the choice to present entry to particular S3 buckets and choose an S3 bucket in the identical AWS Area. Then, I select Create IAM function as default to finish the creation of the function and to robotically use it because the default function 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 take a look at, just a few pattern databases (together with the one I’m utilizing right here) are already out there within the sample_data_dev database. Notice additionally that loading knowledge into Amazon Redshift shouldn’t be 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 concert events.

Sample database tables relations

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.

Console screenshot.

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 function.

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 seek out the highest 5 sellers for occasions primarily based in California (notice 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;

Console screenshot.

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 robotically created each half-hour and saved for twenty-four hours. That may be helpful to get well knowledge in case of unintentional writes or deletes.

Console screenshot.

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 assets. On this tab, I may allow audit logging and export the consumer, connection, and consumer exercise logs to CloudWatch Logs.

Console screenshot.

Within the Datashares tab, I can create a datashare to share knowledge with different namespaces and AWS accounts in the identical or totally different Areas. On this tab, I may 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 Change.

Console screenshot.

Once I create a datashare, I can choose which objects to incorporate. For instance, right here I wish to share solely the date and occasion tables as a result of they don’t comprise delicate knowledge.

Console screenshot.

Utilizing and Configuring Workgroups
Workgroups are collections of compute assets 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 allow Enhanced VPC routing to route community site visitors between my serverless database and the info repositories I exploit (for instance, the S3 buckets used to load or unload knowledge) by way of 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.

Console screenshot.

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 cope with the next variety of customers. Right here I even have the choice to extend the bottom capability to hurry up my queries or lower it to scale back prices.

On this tab, I may 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 assets. To regulate 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 assets utilized by every question, I exploit Question limits to outing queries working for greater than 60 seconds.
