@cdklabs/generative-ai-cdk-constructs / bedrock / KnowledgeBase

Class: KnowledgeBase

Deploys a Bedrock Knowledge Base and configures a backend by OpenSearch Serverless, Pinecone, Redis Enterprise Cloud or Amazon Aurora PostgreSQL.

Extends

Constructors

new KnowledgeBase()

new KnowledgeBase(scope, id, props): KnowledgeBase

Parameters

scope: Construct

id: string

props: KnowledgeBaseProps

Returns

KnowledgeBase

Overrides

KnowledgeBaseBase.constructor

Properties

description

readonly description: string

The description knowledge base.


env

readonly env: ResourceEnvironment

The environment this resource belongs to. For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

Inherited from

KnowledgeBaseBase.env


instruction?

readonly optional instruction: string

A narrative instruction of the knowledge base.


knowledgeBaseArn

readonly knowledgeBaseArn: string

The ARN of the knowledge base.

Overrides

KnowledgeBaseBase.knowledgeBaseArn


knowledgeBaseId

readonly knowledgeBaseId: string

The ID of the knowledge base.

Overrides

KnowledgeBaseBase.knowledgeBaseId


knowledgeBaseInstance

readonly knowledgeBaseInstance: CfnKnowledgeBase

Instance of knowledge base.


knowledgeBaseState

readonly knowledgeBaseState: string

Specifies whether to use the knowledge base or not when sending an InvokeAgent request.


name

readonly name: string

The name of the knowledge base.


node

readonly node: Node

The tree node.

Inherited from

KnowledgeBaseBase.node


physicalName

protected readonly physicalName: string

Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.

This value will resolve to one of the following:

Inherited from

KnowledgeBaseBase.physicalName


role

readonly role: IRole

The role the Knowledge Base uses to access the vector store and data source.

Overrides

KnowledgeBaseBase.role


stack

readonly stack: Stack

The stack in which this resource is defined.

Inherited from

KnowledgeBaseBase.stack


vectorStore

readonly vectorStore: ExistingAmazonAuroraVectorStore | AmazonAuroraVectorStore | VectorCollection | PineconeVectorStore

The vector store for the knowledge base.

Methods

_enableCrossEnvironment()

_enableCrossEnvironment(): void

Internal

Called when this resource is referenced across environments (account/region) to order to request that a physical name will be generated for this resource during synthesis, so the resource can be referenced through its absolute name/arn.

Returns

void

Inherited from

KnowledgeBaseBase._enableCrossEnvironment


addConfluenceDataSource()

addConfluenceDataSource(props): ConfluenceDataSource

Add a Confluence data source to the knowledge base.

Parameters

props: ConfluenceDataSourceAssociationProps

Returns

ConfluenceDataSource

Inherited from

KnowledgeBaseBase.addConfluenceDataSource


addS3DataSource()

addS3DataSource(props): S3DataSource

Add an S3 data source to the knowledge base.

Parameters

props: S3DataSourceAssociationProps

Returns

S3DataSource

Inherited from

KnowledgeBaseBase.addS3DataSource


addSalesforceDataSource()

addSalesforceDataSource(props): SalesforceDataSource

Add a Salesforce data source to the knowledge base.

Parameters

props: SalesforceDataSourceAssociationProps

Returns

SalesforceDataSource

Inherited from

KnowledgeBaseBase.addSalesforceDataSource


addSharePointDataSource()

addSharePointDataSource(props): SharePointDataSource

Add a SharePoint data source to the knowledge base.

Parameters

props: SharePointDataSourceAssociationProps

Returns

SharePointDataSource

Inherited from

KnowledgeBaseBase.addSharePointDataSource


addWebCrawlerDataSource()

addWebCrawlerDataSource(props): WebCrawlerDataSource

Add a web crawler data source to the knowledge base.

Parameters

props: WebCrawlerDataSourceAssociationProps

Returns

WebCrawlerDataSource

Inherited from

KnowledgeBaseBase.addWebCrawlerDataSource


applyRemovalPolicy()

applyRemovalPolicy(policy): void

Apply the given removal policy to this resource

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters

policy: RemovalPolicy

Returns

void

Inherited from

KnowledgeBaseBase.applyRemovalPolicy


associateToAgent()

associateToAgent(agent): void

Associate knowledge base with an agent

Parameters

agent: Agent

Returns

void


generatePhysicalName()

protected generatePhysicalName(): string

Returns

string

Inherited from

KnowledgeBaseBase.generatePhysicalName


getResourceArnAttribute()

protected getResourceArnAttribute(arnAttr, arnComponents): string

Returns an environment-sensitive token that should be used for the resource’s “ARN” attribute (e.g. bucket.bucketArn).

Normally, this token will resolve to arnAttr, but if the resource is referenced across environments, arnComponents will be used to synthesize a concrete ARN with the resource’s physical name. Make sure to reference this.physicalName in arnComponents.

Parameters

arnAttr: string

The CFN attribute which resolves to the ARN of the resource. Commonly it will be called “Arn” (e.g. resource.attrArn), but sometimes it’s the CFN resource’s ref.

arnComponents: ArnComponents

The format of the ARN of this resource. You must reference this.physicalName somewhere within the ARN in order for cross-environment references to work.

Returns

string

Inherited from

KnowledgeBaseBase.getResourceArnAttribute


getResourceNameAttribute()

protected getResourceNameAttribute(nameAttr): string

Returns an environment-sensitive token that should be used for the resource’s “name” attribute (e.g. bucket.bucketName).

Normally, this token will resolve to nameAttr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

Parameters

nameAttr: string

The CFN attribute which resolves to the resource’s name. Commonly this is the resource’s ref.

Returns

string

Inherited from

KnowledgeBaseBase.getResourceNameAttribute


toString()

toString(): string

Returns a string representation of this construct.

Returns

string

Inherited from

KnowledgeBaseBase.toString


fromKnowledgeBaseAttributes()

static fromKnowledgeBaseAttributes(scope, id, attrs): IKnowledgeBase

Parameters

scope: Construct

id: string

attrs: KnowledgeBaseAttributes

Returns

IKnowledgeBase


isConstruct()

static isConstruct(x): x is Construct

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters

x: any

Any object

Returns

x is Construct

true if x is an object created from a class which extends Construct.

Inherited from

KnowledgeBaseBase.isConstruct


isOwnedResource()

static isOwnedResource(construct): boolean

Returns true if the construct was created by CDK, and false otherwise

Parameters

construct: IConstruct

Returns

boolean

Inherited from

KnowledgeBaseBase.isOwnedResource


isResource()

static isResource(construct): construct is Resource

Check whether the given construct is a Resource

Parameters

construct: IConstruct

Returns

construct is Resource

Inherited from

KnowledgeBaseBase.isResource
