# Invoking a Lambda function from an Amazon Aurora MySQL DB cluster
<a name="AuroraMySQL.Integrating.Lambda"></a><a name="lambda"></a>

You can invoke an AWS Lambda function from an Amazon Aurora MySQL-Compatible Edition DB cluster with the native function `lambda_sync` or `lambda_async`. Before invoking a Lambda function from an Aurora MySQL, the Aurora DB cluster must have access to Lambda. For details about granting access to Aurora MySQL, see [Giving Aurora access to Lambda](AuroraMySQL.Integrating.LambdaAccess.md). For information about the `lambda_sync` and `lambda_async` stored functions, see [Invoking a Lambda function with an Aurora MySQL native function](AuroraMySQL.Integrating.NativeLambda.md). 

 You can also call an AWS Lambda function by using a stored procedure. However, using a stored procedure is deprecated. We strongly recommend using an Aurora MySQL native function if you are using one of the following Aurora MySQL versions: 
+ Aurora MySQL version 2, for MySQL 5.7-compatible clusters.
+ Aurora MySQL version 3.01 and higher, for MySQL 8.0-compatible clusters. The stored procedure isn't available in Aurora MySQL version 3.

For information about giving Aurora access to Lambda and invoking a Lambda function, see the following topics.
