When you work with AWS Aurora you have limited admin privileges. There are some different grants for MySQL including SELECT INTO S3 and LOAD FROM S3 that replace the loss of functionality to SELECT INTO OUTFILE and mysqldump/mysqlimport using a delimited format. While I know and use lambda capabilities, I have never executed anything with INVOKE LAMDBA directly from the database.
This week I found out about INVOKE COMPREHEND
(had to look that product up), and INVOKE SAGEMAKER
(which I used independently). These are machine learning capabilities that enable you to build custom integrations using Comprehend
and SageMaker
. I did not have any chance to evaluate these capabilities so I am unable to share any use cases or experiences. There are two built-in comprehend functions aws_comprehend_detect_sentiment() and aws_comprehend_detect_sentiment_confidence(), a likely future starting place. Sagemaker is invoked as an extension of a CREATE FUNCTION that provides the ALIAS AWS_SAGEMAKER_INVOKE_ENDPOINT syntax.
Also available are some MySQL status variables including Aurora_ml_logical_response_cnt, Aurora_ml_actual_request_cnt, Aurora_ml_actual_response_cnt, Aurora_ml_cache_hit_cnt, Aurora_ml_single_request_cnt.
Some googling found an interesting simple example , calculating the positive/negative sentiment and confidence of sentences of text. I could see this as useful for analyzing comments. I’ve included the example from this site here to encourage my readers to take a look as I plan to do. Post IAM configuration I will be really curious to evaluate the responsiveness of this example. Is this truly a batch only operation or could you return some meaningful response timely?
