You have probably seen architectures that use DynamoDB streams to perform change data capture on tables and Lambda functions to process those changes before. Today, we’ll do a deep dive into the underlying technology and explore how we can configure and tweak this configuration to our advantage.
This point explains how to work around Glue’s problem of selective amnesia when creating Dynamic Frames from the Glue data catalog.
In this post I’ll show you how to trigger your Lambda functions in intervals smaller than a minute using StepFunctions and the CDK.
Working with CSV files and Big Data tools such as AWS Glue and Athena can lead to interesting challenges. In this blog I will explain to you how to solve a particular problem that I encountered in a project - the HIVE_PARTITION_SCHEMA_MISMATCH.
Lambda Event filters are a great addition to our serverless toolbox and allow us to both simplify our code as well as save money. That’s great, but they can also delete messages from your SQS-queues if you’re note careful. In this post I’m going to show you what to watch out for.
Detect the crack in the window (or the lambda library) before it breaks: As we have seen during the last month, also well known libraries like log4j can have previously unknown vulnerabilities. Therefore scanning your Lambda application before deploying is not enough! What happens if a new cybersecurity vulnerability occurs while your functions are running? Solution: Amazon Inspector. Only problem: it`s not available for Lambda yet. Fortunately, you can deploy Lambda with container images and Inspector will continuously scan these images for you. Want to know how set up Lambda & Inspector and see how evil Node vulnerabilities are detected? Read on!
In this post I’m going to explore how the new event filters in AWS Lambda can be used to implement the data model for a video streaming website in DynamoDB. I’ll explain why this feature makes your code simpler and allows you to save money in the process.
The CDK Book The CDK Book “A Comprehensive Guide to the AWS Cloud Development Kit” is a book by Sathyajith Bhat, Matthew Bonig, Matt Coulter, Thorsten Hoeger written end of 2021. Because the CDK itself is polyglott with jsii, the TypeScript examples are automatically translated in other languages. So the example CDK code used in the book is jsii generated, and there are samples for TypeScript, Python, Java and C#.
