Amazon Aurora (MySQL) 的 Stored Procedure 可以跑 AWS Lambda...

查了資料才發現去年十月 Amazon Aurora (MySQL-Compatible Edition) 就支援用 AWS Lambda 當 stored procedure 了,只是當時只支援 async mode,能做的事情比較有限:「Amazon Aurora New Features: AWS Lambda Integration and Data Load from Amazon S3 to Aurora Tables」。

Now you can invoke Lambda functions directly from within an Aurora database via stored procedures or user-defined functions. Lambda integration allows you to extend the capabilities of the database and invoke external applications to act upon data changes. For example, you can create a Lambda function that sends emails to customers whenever their address in the database is updated.

前幾天發表的則是支援 sync mode,可以等到:「Amazon Aurora with MySQL Compatibility Natively Supports Synchronous Invocation of AWS Lambda Functions」。

Starting with version 1.16, we are extending this feature to be able to able to synchronously invoke Lambda functions.

Use the native function lambda_sync when you must know the result of the execution before moving on to another action.

這解掉了 MySQL 的 stored procedure 一直很殘的問題...
