# AWS::Bedrock::KnowledgeBase VectorKnowledgeBaseConfiguration
<a name="aws-properties-bedrock-knowledgebase-vectorknowledgebaseconfiguration"></a>

Contains details about the model used to create vector embeddings for the knowledge base.

## Syntax
<a name="aws-properties-bedrock-knowledgebase-vectorknowledgebaseconfiguration-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-bedrock-knowledgebase-vectorknowledgebaseconfiguration-syntax.json"></a>

```
{
  "[EmbeddingModelArn](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelarn)" : String,
  "[EmbeddingModelConfiguration](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelconfiguration)" : EmbeddingModelConfiguration,
  "[SupplementalDataStorageConfiguration](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-supplementaldatastorageconfiguration)" : SupplementalDataStorageConfiguration
}
```

### YAML
<a name="aws-properties-bedrock-knowledgebase-vectorknowledgebaseconfiguration-syntax.yaml"></a>

```
  [EmbeddingModelArn](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelarn): String
  [EmbeddingModelConfiguration](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelconfiguration): 
    EmbeddingModelConfiguration
  [SupplementalDataStorageConfiguration](#cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-supplementaldatastorageconfiguration): 
    SupplementalDataStorageConfiguration
```

## Properties
<a name="aws-properties-bedrock-knowledgebase-vectorknowledgebaseconfiguration-properties"></a>

`EmbeddingModelArn`  <a name="cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelarn"></a>
The Amazon Resource Name (ARN) of the model used to create vector embeddings for the knowledge base.  
*Required*: Yes  
*Type*: String  
*Pattern*: `^(arn:aws(-[^:]+)?:[a-z0-9-]+:[a-z0-9-]{1,20}:[0-9]{0,12}:[a-zA-Z0-9-:/._+]+)$`  
*Minimum*: `20`  
*Maximum*: `2048`  
*Update requires*: [Replacement](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`EmbeddingModelConfiguration`  <a name="cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-embeddingmodelconfiguration"></a>
The embeddings model configuration details for the vector model used in Knowledge Base.  
*Required*: No  
*Type*: [EmbeddingModelConfiguration](aws-properties-bedrock-knowledgebase-embeddingmodelconfiguration.md)

`SupplementalDataStorageConfiguration`  <a name="cfn-bedrock-knowledgebase-vectorknowledgebaseconfiguration-supplementaldatastorageconfiguration"></a>
If you include multimodal data from your data source, use this object to specify configurations for the storage location of the images extracted from your documents. These images can be retrieved and returned to the end user. They can also be used in generation when using [RetrieveAndGenerate](https://docs.amazonaws.cn/bedrock/latest/APIReference/API_agent-runtime_RetrieveAndGenerate.html).  
*Required*: No  
*Type*: [SupplementalDataStorageConfiguration](aws-properties-bedrock-knowledgebase-supplementaldatastorageconfiguration.md)  
*Update requires*: [Replacement](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)
