`AccessConfigs`  <a name="cfn-lambda-eventsourcemapping-schemaregistryconfig-accessconfigs"></a>
An array of access configuration objects that tell Lambda how to authenticate with your schema registry.  
*Required*: No

`SchemaRegistryURI`  <a name="cfn-lambda-eventsourcemapping-schemaregistryconfig-schemaregistryuri"></a>

`SchemaValidationConfigs`  <a name="cfn-lambda-eventsourcemapping-schemaregistryconfig-schemavalidationconfigs"></a>
An array of schema validation configuration objects, which tell Lambda the message attributes you want to validate and filter using your schema registry.  
*Required*: No  
*Type*: Array of [SchemaValidationConfig](aws-properties-lambda-eventsourcemapping-schemavalidationconfig.md)  
*Minimum*: `1`  
*Maximum*: `2`
