In this week’s TechChat, we welcome Keith Gregory, our Cloud & Data Engineering Practice Lead here at Chariot. Keith is a prolific writer both on the Chariot blog as well as on his own, and is a wealth of knowledge on all things AWS. We touch on Redshift execution plans, how to appropriately size Redshift … Read More
In this post I walk through several execution plans, explain what Redshift is doing in each, and highlight the parts of plans that indicate problems.
Today we welcome Keith Gregory to the show! Keith is our AWS Practice Lead here at Chariot. We cover some announcements from AWS re:Invent, and do a deep dive into CodeCatalyst, OpenSearch Serverless, Lambda Snapstart, Redshift streaming ingestion from Kafka/Kinesis, and EventBridge Pipes.
Amazon Redshift’s launch in 2012 was one of the “wow!” moments in my experience with AWS. Here was a massively parallel database system that could be rented for 25 cents per node-hour. Here we are in 2021, and AWS has just announced Redshift Serverless, in which you pay for the compute and storage that you use, rather than a fixed monthly cost for a fixed number of nodes with a fixed amount of storage. And for a lot of use cases, I think that’s a great idea. So I spent some time kicking the tires, and this is what I learned.
Is Amazon’s new managed, lower cost, petabyte scale warehousing solution a game changer? We’ll review the costs and discuss what does (or does not) make Amazon Redshift reliable, scalable and effective. We’ll dive into the technical details behind the query and storage engines and we’ll expose what works well and what does not. This talk should benefit both those that are and are not already part of the Amazon Web Services ecosystem.
