8. After the desk view hundreds, select Create desk to start out creating the desk.

9. Within the editor, enter the identify of the desk. We name this desk examples.
10. Select the catalog (:s3tablescatalog/redshifticeberg) and database (icebergsons3).

Subsequent, add columns to your desk.

11. Within the Schema part, select Add column, and add a column that represents an ID.

12. Repeat this step and add columns for extra information:
    1. category_id (lengthy)
    2. insert_date (date)
    3. information (string)

The ultimate schema appears like the next screenshot.

13. Select Submit to create the desk.

Subsequent, you want to arrange a read-only permission so you possibly can question Iceberg information in S3 Tables utilizing the Amazon Redshift Question Editor v2. For extra info, see Stipulations for managing Amazon Redshift namespaces within the AWS Glue Information Catalog.

14. Beneath Administration within the navigation pane, select Administrative roles and duties.
15. Within the Information lake directors part, select Add.

16. For Entry kind, choose Learn-only administrator.
17. For IAM customers and roles, enter AWSServiceRoleForRedshift.

AWSServiceRoleForRedshift is a service-linked position that’s managed by AWS.

18. Select Affirm.

You could have now configured SageMaker Lakehouse utilizing Lake Formation to permit Amazon Redshift to question Iceberg tables in S3 Tables. Subsequent, you populate some information into the Iceberg desk, and question it with Amazon Redshift.

Use SQL to question Iceberg information with Amazon Redshift

For this instance, we use Athena to load information into our Iceberg desk. That is one choice for ingesting information into an Iceberg desk; see Utilizing Amazon S3 Tables with AWS analytics providers for different choices, together with Amazon EMR with Spark, Amazon Information Firehose, and AWS Glue ETL.

1. On the Athena console, navigate to the question editor.
2. If that is your first time utilizing Athena, it’s essential to first specify a question outcome location earlier than executing your first question.
3. Within the question editor, below Information, select your information supply (AwsDataCatalog).
4. For Catalog, select the desk bucket you created (s3tablescatalog/redshifticeberg).
5. For Database, select the database you created (icebergsons3).

6. Let’s execute a question to generate information for the examples desk. The next question generates over 1.5 million rows akin to 30 days of knowledge. Enter the question and select Run.

INSERT INTO icebergsons3.examples
SELECT
    b.id * (date_diff('day', CURRENT_DATE, a.insert_date) + 1),
    b.id % 1000, a.insert_date,
    CAST(random() AS varchar)
FROM
    unnest(
        sequence(CURRENT_DATE, CURRENT_DATE + INTERVAL '30' DAY, INTERVAL '1' DAY)
    ) AS a(insert_date),
    unnest(sequence(1, 50000)) AS b(id);

The next screenshot exhibits our question.

The question takes about 10 seconds to execute.

Now you need to use Redshift Serverless to question the info.

7. On the Redshift Serverless console, provision a Redshift Serverless workgroup for those who haven’t already completed so. For directions, see Get began with Amazon Redshift Serverless information warehouses information. On this instance, we use a Redshift Serverless workgroup referred to as iceberg.
8. Guarantee that your Amazon Redshift patch model is patch 188 or greater.

9. Select Question information to open the Amazon Redshift Question Editor v2.

10. Within the question editor, select the workgroup you need to use.

A pop-up window will seem, prompting what person to make use of.

11. Choose Federated person, which is able to use your present account, and select Create connection.

It’ll take a couple of seconds to start out the connection. Whenever you’re linked, you will note a listing of obtainable databases.

12. Select Exterior databases.

You will note the desk bucket from S3 Tables within the view (on this instance, that is redshifticeberg@s3tablescatalog).

13. Should you proceed clicking via the tree, you will note the examples desk, which is the Iceberg desk you beforehand created that’s saved within the desk bucket.

Now you can use Amazon Redshift to question the Iceberg desk in S3 Tables.

Earlier than you execute the question, overview the Amazon Redshift syntax for querying catalogs registered in SageMaker Lakehouse. Amazon Redshift makes use of the next syntax to reference a desk: database@namespace.schema.desk or database@namespace".schema.desk.

On this instance, we use the next syntax to question the examples desk within the desk bucket: redshifticeberg@s3tablescatalog.icebergsons3.examples.

Study extra about this mapping in Utilizing Amazon S3 Tables with AWS analytics providers.

Let’s run some queries. First, let’s see what number of rows are within the examples desk.

14. Run the next question within the question editor:

SELECT depend(*)
FROM redshifticeberg@s3tablescatalog.icebergsons3.examples; 

The question will take a couple of seconds to execute. You will note the next outcome.

Let’s attempt a barely extra sophisticated question. On this case, we need to discover all the times that had instance information beginning with 0.2 and a category_id between 50–75 with no less than 130 rows. We are going to order the outcomes from most to least.

15. Run the next question:

SELECT examples.insert_date, depend(*)
FROM redshifticeberg@s3tablescatalog.icebergsons3.examples
WHERE
    examples.information LIKE '0.2%' AND
    examples.category_id BETWEEN 50 AND 75
GROUP BY examples.insert_date
HAVING depend(*) > 130
ORDER BY depend DESC;

You would possibly see totally different outcomes than the next screenshot due the randomly generated supply information.
