PackYakPackyak AWS CDKPackYak is a next-generation framework for building and deploying Data Lakehouses in AWS with a Git-like versioned developer workflow that simplifies how Data Scientists and Data Engineers collaborate.It enables you to deploy your entire Data Lakehouse, ETL and Machine Learning platforms on AWS with no external dependencies, maintain your Data Tables with Git-like versioning semantics and scale data production with Dagster-like Software-defined Asset Graphs.It combines 5 key technologies into one framework that makes scaling Data Lakehouses and Data Science teams dead simple:Git-like versioning of Data Tables withProject Nessie- no more worrying about the version of data, simply use branches, tags and commits to freeze data or roll back mistakes.Software-defined Assets (as seen in Dagster) - think of your data pipelines in terms of the data it produces. Greatly simplify how data is produced, modified over time and backfilled in the event of errors.Infrastructure-as-Code (AWS CDK and Pulumi) - deploy in minutes and manage it all yourself with minimal effort.Apache Spark - write your ETL as simple python processes that are then scaled automatically over a managed AWS EMR Spark Cluster.Streamlit - build Streamlit applications that integrate the Data Lakehouse and Apache Spark to provide interactive reports and exploratory tools over the versioned data lake.Get StartedInstall DockerIf you haven't already, installDocker.Install Python Poetry & Plugins# Install the Python Poetry CLIcurl-sSLhttps://install.python-poetry.org|python3-# Add the export plugin to generate narrow requirements.txtpoetryselfaddpoetry-plugin-exportInstall thepackyakCLI:pipinstallpackyakCreate a new Projectpackyaknewmy-projectcd./my-projectDeploy to AWSpoetryruncdkdeployGit-like Data Catalog (Project Nessie)PackYak comes with a Construct for hosting aProject Nessiecatalog that supports Git-like versioning of the tables in a Data Lakehouse.It deploys with an AWS DynamoDB Versioned store and an API hosted in AWS Lambda or AWS ECS.
