Latest open source projects


Babelfish last week saw the availability of the Babelfish for PostgreSQL open source project. As a reminder, Babelfish for PostgreSQL is an open source project available under the Apache 2.0 and PostgreSQL licenses that provide the capability for PostgreSQL to understand queries from applications written for Microsoft SQL Server. You can get started by reading my colleague Sebastian Stormacq post, Goodbye Microsoft SQL Server, Hello Babelfish. We also had Chandra sekhar Pathivada and Yogi Barot share this post, Modify SSIS packages from SQL Server to Babelfish for Aurora PostgreSQL showing you how to modify your existing Microsoft SSIS package connection from SQL Server to Babelfish.



nixtla this open source library from Nixtla looks interesting. An open source time series forecasting library. You can use the service that Nixtla provide, or use the documentation within the README to host yourself on AWS. Either way, if you are exploring your choices for a time series forecasting library, you should add this to your list.


Stefan Sundin has been busy, putting together a couple of open source projects and a blog post to show you how to use them, Introducing shrimp and s3sha256sum


shrimp this open source tool helps you upload large files to Amazon S3 over slow connections. Shrimp is optimised for this use case.


s3sha256sum this open source tool is a small program that calculates SHA256 checksums of objects stored on Amazon S3. Use it to verify the integrity of your objects. Perfect for checking those files have copied successfully (large files that you may have copied using Shrimp perhaps!)

Nice work Stefan!


aws-sso-cli this open source, GPL 3 project from Aaron Turner is a secure replacement for using the aws configure sso wizard with a focus on security and ease of use for organisations with many AWS Accounts and/or users with many IAM Roles to assume. Detailed docs and examples, worth checking out.


aws-cdk-go-example-static-site if you are looking for an example of how to deploy statics sites via AWS CDK, then check out this project from Saul Magnusson. This example launches a secure static site hosted in an S3 bucket, distributed by CloudFront, protected by an ACM certificate, and with URIs automatically rewritten by a CloudFront Function


ds-dashboard Andrea Di Simone and Samuel Passman have put together this project that helps you to deploy and operate a simple data collection and distribution mechanism for your data science projects, which can be used for use cases such as generating dashboards. For a detailed walk through, check out the blog post, Implementing a hub and spoke dashboard for multi-account data science projects


amazon-opensearch-service-monitor if you are using OpenSearch, then check out this repository that contains step by step demonstration to setup monitoring Stack for Amazon OpenSearch Service domains across all specified regions. This example uses AWS CDK and Python.


AWS and Community blog posts


In the post Achieving least-privilege at FollowAnalytics with Repokid, Aardvark and ConsoleMe, Guilherme Sena Zuza shares how he used a number of open source tools to help get closer to the principle of least privilege, and how he deployed these tools at FollowAnalytics. [hands on]



A couple of OpenSearch related posts this week.

First up we have Anton Rubin from Eliatra, who explains some of the core concepts of OpenSearch security in the post, Partner Highlight: Eliatra presents OpenSearch Security Concepts. The post links to other, deeper dives if you want to gain even more understanding.


Following that we have the post Moving from open source Elasticsearch to OpenSearch, where Sarat Vemulapalli shares how an overview of how to move from open source Elasticsearch to OpenSearch.

Apache Airflow

I missed this the first time around, but caught it last week. Suman Kumar Gangopadhyay provides a step by step guide to help setup a pipeline which can automate running spark jobs from an edge node to a spark cluster, in the blog postAirflow, Spark & S3, stitching it all together [hands on]

Apache DistCp

In the post, Copy large datasets from Google Cloud Storage to Amazon S3 using Amazon EMR Andrew Lee and Hammad Ausaf demonstrates how to configure an EMR cluster to use open source tools such as Apache DistCp and S3DistCP, and compares the performance of doing large file copies. [hands on]

Delta Sharing

Delta Sharing is a Linux Foundation open source framework that uses an open protocol to secure the real-time exchange of large datasets and enables secure data sharing across products for the first time. It was great therefore, to read Delta Sharing on AWS from former colleague Frank Munz, who is now a Developer Advocate at Databricks. [hands on]


Apache Solr

Apache Solr is an open source enterprise search platform built on Apache Lucene. Kinnar Kumar Sen, Anjan Biswas, and Ananth Raghavendra have collaborated on this post, Deploying and scaling Apache Solr on Kubernetes that shows you how to deploy a highly available, scalable, and fault-tolerant enterprise-grade search platform with Apache Solr using Amazon Elastic Kubernetes Service (Amazon EKS). [hands on]



PyDeequ is an open-source Python wrapper over Deequ (an open-source tool developed and used at Amazon, to help data scientists and engineers with data quality and testing capabilities from Python and PySpark). In the post, Accelerate large-scale data migration validation using PyDeequ Mahendar Gajula and Nitin Srivastava, show you how you can use this and walk through a step-by-step process to validate large datasets. [hands on]


Synchro Charts

Synchro Charts, is a new open source project that is a front-end component library that provides a collection of components to visualise time-series data for application developers with a focus on monitoring, root cause analysis, and analytics. In the post, Visualizing time series data with the open source Synchro Charts Brian Diehr walks you through some of the features which you can check out at


Amazon EKS adds native support for Bottlerocket in Managed Node Groups from Sheetal Joshi takes a look at how to set up an Amazon EKS cluster and launch a Bottlerocket managed node group. Bottlerocket is a Linux-based open-source operating system that is purpose-built by Amazon. It focuses on security and maintainability, and provides a reliable, consistent, and safe platform for container-based workloads. Dive deeper into what this means by checking out this post. [hands on]

Serverless Framework

AWS Community Builder Sebastian Bille takes a look at two open source projects and how you get combine these when developing and deploying your serverless application in the blog post, Combining Serverless Framework & AWS CDK [hands on]


Eric Johnson shares with you a new capability of AWS SAM, that aims to increase infrastructure accuracy for testing with sam sync, incremental builds, and aggregated feedback for developers. AWS SAM Accelerate brings the developer to the cloud and not the cloud to the developer. In the post, Accelerating serverless development with AWS SAM Accelerate he shows you how to bypass most local emulation by testing serverless applications in the cloud against production services using AWS SAM Accelerate. When I saw a demo of this, this was one of the most exciting things I have seen in a while. If you are a serverless developer, you should definitely check this out. [hands on]


GitHub Actions

If you are looking to use GitHub Actions to build your open source projects and need to integrate with AWS, then the recent release of the of Github Actions OpenID Connect will be good news for you. In this blog post, Using Github Actions OpenID Connector to push to AWS ECR without Credentials Robert Hafner walks you through setting this up, using an example of using Terraform to push images to Amazon ECR. Also, check out the videos where we have Richard Boyd walking you through how you can set this up.

Quick updates


Amazon Elastic Kubernetes Service (EKS) now adds native support for Bottlerocket in EKS managed node groups in all commercial AWS regions. Most EKS customers today deploy their applications on worker nodes backed by operating systems that are designed for a variety of use cases. AWS launched Bottlerocket, a minimal, Linux-based open source operating system that is purpose built and optimised to run containers. When combined, EKS managed node groups and Bottlerocket give customers a simple way to provision and manage compute capacity using the latest best practices for running containers in production. Bottlerocket is now included as a built-in AMI choice for managed node groups, enabling customers to provision container optimised worker nodes with a single click.

EKS customers can easily migrate their applications to run on Bottlerocket based worker nodes and benefit from an improved node security posture. By moving to worker nodes that include only the minimal set of packages needed to run containers, customers benefit from a reduced attack surface, decreased node provisioning time and improved efficiency as more node resources are allocated to applications. This improves cluster utilisation and scale. Managed node groups provides notifications when newer EKS Bottlerocket AMIs are available, enabling customers to more easily update nodes to the latest versions of the software.


A couple of quick updates this week:

Following the announcement of updates to the PostgreSQL database by the open source community, we have updated Amazon Aurora PostgreSQL-Compatible Edition to support PostgreSQL 13.4, 12.8, 11.13, and 10.18. These releases contain bug fixes and improvements by the PostgreSQL community. As a reminder, Amazon Aurora PostgreSQL 9.6 will reach end of life on January 31, 2022.

Following that, we saw news that Amazon Aurora PostgreSQL-Compatible Edition now supports PostGIS major version 3.1. This new version of PostGIS is available on PostgreSQL versions 13.4, 12.8, 11.13, 10.18, and higher. PostGIS allows you to store, query and analyze geospatial data within a PostgreSQL database. PostGIS 3.1 significantly improves performance such as spatial joins, which now run up to [N]X faster on PostgreSQL 13. As an example, you could use a spatial join to count the number of people living in an area defined by the reception of mobile phones from radio towers. PostGIS 3.1 is the new default version on PostgreSQL 10 and higher starting with the new minor versions. However, you can still create older versions of PostGIS in your PostgreSQL database, e.g., if you require version stability.

Video of the week

We have a bumper selection this week, all great and well worth watching.

Building Open Data Lakes

From blog posts to You Tube, there is no place where Gary Stafford will not go in order to share his knowledge and expertise on this topic. In this video (grab a cup of your favourite hot beverage) he shows you how you can build a simple open data lake on AWS using a combination of open-source software, including Debezium for change data capture (CDC), Apache Kafka, Kafka Connect, Apache Hive, Apache Spark, and Apache Hudi and Hudi's DeltaStreamer.


Fresh from the AWS Summit in DC, we have Tyler Lynch and Drew Mullen talking about the process of contributing upstream to the AWS provider for Terraform. Dive deep on overcoming imposter syndrome, understanding the process, validating the need, working on the code, acceptance tests, and making a pull request.

Deploying to AWS with GitHub Actions

This talk from one of my colleagues Richard Boyd, will walk you through how you can use a recently announced new capabilities (new OIDC provider as well as some new AWS developed custom GitHub actions) to show you how to deploy a serverless application using AWS SAM.
