End of support notice: On October 7, 2026, AWS will end support for Amazon FinSpace. After October 7, 2026, you will no longer be able to access the FinSpace console or FinSpace resources. For more information, see Amazon FinSpace end of support.

After careful consideration, we decided to end support for Amazon FinSpace, effective October 7, 2026. Amazon FinSpace will no longer accept new customers beginning October 7, 2025. As an existing customer with an Amazon FinSpace environment created before October 7, 2025, you can continue to use the service as normal. After October 7, 2026, you will no longer be able to use Amazon FinSpace. For more information, see Amazon FinSpace end of support.

CreateKxDataview

Creates a snapshot of kdb database with tiered storage capabilities and a pre-warmed cache, ready for mounting on kdb clusters. Dataviews are only available for clusters running on a scaling group. They are not supported on dedicated clusters.

URI Request Parameters

The request uses the following URI parameters.

databaseName

The name of the database where you want to create a dataview.

Length Constraints: Minimum length of 3. Maximum length of 63.

Pattern: ^[a-zA-Z0-9][a-zA-Z0-9-_]*[a-zA-Z0-9]$

Required: Yes

environmentId

A unique identifier for the kdb environment, where you want to create the dataview.

Length Constraints: Minimum length of 1. Maximum length of 32.

Pattern: .*\S.*

Required: Yes

Request Body

The request accepts the following data in JSON format.

azMode

The number of availability zones you want to assign per volume. Currently, FinSpace only supports SINGLE for volumes. This places dataview in a single AZ.

Type: String

Valid Values: SINGLE | MULTI

Required: Yes

clientToken

A token that ensures idempotency. This token expires in 10 minutes.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[a-zA-Z0-9-]+$

Required: Yes

dataviewName

A unique identifier for the dataview.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 63.

Pattern: ^[a-zA-Z0-9][a-zA-Z0-9-_]*[a-zA-Z0-9]$

Required: Yes

autoUpdate

The option to specify whether you want to apply all the future additions and corrections automatically to the dataview, when you ingest new changesets. The default value is false.

Type: Boolean

Required: No

availabilityZoneId

The identifier of the availability zones.

Type: String

Length Constraints: Minimum length of 8. Maximum length of 12.

Pattern: ^[a-zA-Z0-9-]+$

Required: No

changesetId

A unique identifier of the changeset that you want to use to ingest data.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 26.

Pattern: ^[a-zA-Z0-9]+$

Required: No

description

A description of the dataview.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1000.

Pattern: ^[a-zA-Z0-9. ]{1,1000}$

Required: No

readWrite

The option to specify whether you want to make the dataview writable to perform database maintenance. The following are some considerations related to writable dataviews.



  • You cannot create partial writable dataviews. When you create writeable dataviews you must provide the entire database path.

  • You cannot perform updates on a writeable dataview. Hence, autoUpdate must be set as False if readWrite is True for a dataview.

  • You must also use a unique volume for creating a writeable dataview. So, if you choose a volume that is already in use by another dataview, the dataview creation fails.

  • Once you create a dataview as writeable, you cannot change it to read-only. So, you cannot update the readWrite parameter later.

Type: Boolean

Required: No

segmentConfigurations

The configuration that contains the database path of the data that you want to place on each selected volume. Each segment must have a unique database path for each volume. If you do not explicitly specify any database path for a volume, they are accessible from the cluster through the default S3/object store segment.

Type: Array of KxDataviewSegmentConfiguration objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

tags

A list of key-value pairs to label the dataview. You can add up to 50 tags to a dataview.

Type: String to string map

Map Entries: Maximum number of 50 items.

Key Length Constraints: Minimum length of 1. Maximum length of 128.

Key Pattern: ^(?!aws:)[a-zA-Z+-=._:/]+$

Value Length Constraints: Minimum length of 1. Maximum length of 256.

Value Pattern: ^[a-zA-Z0-9+-=._:@ ]+$

Required: No
