@cdklabs/generative-ai-cdk-constructs / bedrock / GraphKnowledgeBase
Creates a new Amazon Bedrock Knowledge Base using a Neptune Analytics vector store, this is also known as GraphRAG.
GraphRAG is a capability that combines graph modeling with generative AI to enhance retrieval-augmented generation (RAG). It automatically identifies and leverages relationships between entities and structural elements within documents, enabling more comprehensive and contextually relevant responses from foundation models.

new GraphKnowledgeBase(
scope,id,props):GraphKnowledgeBase
Construct
string
GraphKnowledgeBase
GraphKnowledgeBaseBase.constructor
readonlyoptionaldescription:string
The description of the knowledge base.
GraphKnowledgeBaseBase.description
readonlyembeddingModel:BedrockFoundationModel
The embeddings model for the knowledge base.
readonlyenv: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.
readonlyfieldMapping:VectorFieldMapping
The vector field mapping configuration.
readonlygraph:INeptuneGraph
readonlyoptionalinstruction:string
A narrative instruction of the knowledge base. A Bedrock Agent can use this instruction to determine if it should query this Knowledge Base.
GraphKnowledgeBaseBase.instruction
readonlyknowledgeBaseArn:string
The ARN of the knowledge base.
"arn:aws:bedrock:us-east-1:123456789012:knowledge-base/KB12345678"
GraphKnowledgeBaseBase.knowledgeBaseArn
readonlyknowledgeBaseId:string
The ID of the knowledge base.
"KB12345678"
GraphKnowledgeBaseBase.knowledgeBaseId
readonlyname:string
The name of the knowledge base.
readonlynode:Node
The tree node.
readonlyoptionalnotebook:NeptuneGraphNotebook
protectedreadonlyphysicalName: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:
"my-awesome-bucket")undefined, when a name should be generated by CloudFormationGraphKnowledgeBaseBase.physicalName
readonlyrole:IRole
The role associated with the knowledge base.
readonlystack:Stack
The stack in which this resource is defined.
readonlytype:KnowledgeBaseType=KnowledgeBaseType.VECTOR
The type of knowledge base.
readonlyvectorStoreType:NEPTUNE_ANALYTICS=VectorStoreType.NEPTUNE_ANALYTICS
The storage type for the Vector Embeddings.
GraphKnowledgeBaseBase.vectorStoreType
_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.
void
GraphKnowledgeBaseBase._enableCrossEnvironment
addConfluenceDataSource(
props):ConfluenceDataSource
Add a Confluence data source to the knowledge base.
ConfluenceDataSourceAssociationProps
GraphKnowledgeBaseBase.addConfluenceDataSource

props):CustomDataSource
Add a Custom data source to the knowledge base.
CustomDataSourceAssociationProps
GraphKnowledgeBaseBase.addCustomDataSource
addS3DataSource(
props):S3DataSource
Adds an S3 data source to the knowledge base.
GraphKnowledgeBaseBase.addS3DataSource
addSalesforceDataSource(
props):SalesforceDataSource
Add a Salesforce data source to the knowledge base.
SalesforceDataSourceAssociationProps
GraphKnowledgeBaseBase.addSalesforceDataSource
addSharePointDataSource(
props):SharePointDataSource
Add a SharePoint data source to the knowledge base.

addWebCrawlerDataSource(
props):WebCrawlerDataSource
Add a web crawler data source to the knowledge base.
WebCrawlerDataSourceAssociationProps
GraphKnowledgeBaseBase.addWebCrawlerDataSource
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).
RemovalPolicy
void
GraphKnowledgeBaseBase.applyRemovalPolicy
protectedgeneratePhysicalName():string
string
GraphKnowledgeBaseBase.generatePhysicalName
protectedgetResourceArnAttribute(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.
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
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.
string
GraphKnowledgeBaseBase.getResourceArnAttribute
protectedgetResourceNameAttribute(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.
string
The CFN attribute which resolves to the resource’s name.
Commonly this is the resource’s ref.
string
GraphKnowledgeBaseBase.getResourceNameAttribute

toString():
string
Returns a string representation of this construct.

Construct
string
staticisConstruct(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.

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