Try feeding the data into other data stores, doing full-text search on Elasticsearch or storing metadata in DynamoDB.Ĭapturing Data Changes in Amazon Aurora Using AWS LambdaĮrror: This version of MariaDB doesn't yet support 'multiple triggers with the same action time and event for one table On the Lambda side, it got notified with the necessary information.įor a demonstration code, consider below Python code.įrom here, you are good to go.
To test, I updated and deleted of some test posts. PK), table name to be suitable for your use case. 'arn:aws:lambda:us-west-2:123456789012:function:',įill in the column name, type and attribute, as well as the Lambda function ARN, and the data format that will be sent to Lambda.ĭROP TRIGGER IF EXISTS To_Lambda_Trigger_Update ĭROP TRIGGER IF EXISTS To_Lambda_Trigger_Delete įill in the field name (i.e. In other words, which post is undergo which type of action.Īfter figuring out the necessary data that should be consumed by Lambda, I could continue to configure stored procedure in Aurora. Also, my Lambda function only care about when the interested actions happen, therefore only a few columns need to be sent to Lambda. Login a jump server and connect to the Aurora MySQL server using MySQL workbench.īecause the content of a post could be very large, such data are not suitable to be carried over an async call. If you want to change the DB parameter group associated with a DB instance, you must manually reboot the instance before the new DB parameter group is used by the DB instance.Īfter the Aurora cluster had been restored, specify the IAM role under the cluster. The parameter group was specified to use the one created just now. This role is what the RDS service will asuume to make calls to Lambda.īecause Aurora does not support in-place upgrade, we took a snapshot of the Aurora instance, and re-build a new Aurora cluster from that snapshot, but with verion 5.7 this time. Next, the IAM role ARN specified in the "aws_default_lambda_role" field. (INSERT is not needed in this scenario.) For MySQL, you cannot write UPDATE and DELETE clauses in one trigger statement.īefore upgrading the Aurora engine, a new parameter group should be created, because the default parameter group is not modifiable.

The reason that multiple triggers are needed is that actions should be taken when UPDATE and DELETE happens in the table. Different data services are for different purposes.Īs of MySQL 5.6, multiple triggers are not supported, therefore, the Aurora MySQL engine need to be upgraded from 5.6 to 5.7, to support multiple triggers. After that, stored procedures will trigger async calls to AWS Lambda, where data will be streamed to other data services. Now, contents will be firstly landed on our main DB. This behavior had increased the application burden, and negetively impacted user experiences.ĭuring last weekend, we have changed that behavior from synchronous to asynchronous. This was done by application storing data of different purpose to different data stores synchronously. Prior to today, my web site need to enrich different databases explicitly. The stored procedure isn't available in Aurora MySQL version 3.
Aurora MySQL version 3.01 and higher, for MySQL 8.0-compatible clusters. Aurora MySQL version 2, for MySQL 5.7-compatible clusters. We strongly recommend using an Aurora MySQL native function if you are using one of the following Aurora MySQL versions:
This topic has an update for Aurora MySQL version 3, please refer to post. This post is only for Aurora MySQL version 2.
