Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- How to change the API version from v1alpha to v1 prior to upgrading the kubernetes cluster?

How can we change the API versions of kubernetes objects in GKE prior to cluster upgrade?
Those two resource types are using the traefik.containo.us/v1alpha1 API version, which itself is defined at https://github.com/dask/dask-gateway/blob/main/resources/helm/dask-gateway/crds/traefik.yaml, and doesn't use the deprecated CRD API.

Why Databricks Is Winning
I’ve had a lot of success with Dask lately. It’s comparable to spark in some ways [0]. Being written in python and built on top of pandas/numpy it allows much more flexibility. It also has great tools built on top of kubernetes making deployment quick and easy [1].

Testing spark applications
Unit and e2e tests using a combination of pytest and chispa (https://github.com/MrPowers/chispa). Custom library to create random test data that fits schema with optional hardcoded overrides for relevant fields to test business logic.

Spark open source community is awesome
here's a little README fix a user pushed to chispa

Invitation to collaborate on open source PySpark projects
chispa is a library of PySpark testing functions.

installing pyspark on my m1 mac, getting an env error
The other approach I've used is Poetry, see the chispa project as an example. Poetry is especially nice for projects that you'd like to publish to PyPi because those commands are built-in.

Spark: local dev environment
- All Spark transformations are tested with pytest + chispa (https://github.com/MrPowers/chispa)

Pyspark now provides a native Pandas API
Pandas syntax is far inferior to regular PySpark in my opinion. Goes to show how much data analysts value a syntax that they're already familiar with. Pandas syntax makes it harder to reason about queries, abstract DataFrame transformations, etc. I've authored some popular PySpark libraries like quinn and chispa and am not excited to add Pandas syntax support, haha.

Show dataengineering: beavis, a library for unit testing Pandas/Dask code
I am the author of spark-fast-tests and chispa, libraries for unit testing Scala Spark / PySpark code.

Tips for building popular open source data engineering projects
Blogging has been the main way I've been able to attract users. Someone searches "testing PySpark", they see this blog, and then they're motivated to try chispa.

Ask HN: What are some tools / libraries you built yourself?
I built daria (https://github.com/MrPowers/spark-daria) to make it easier to write Spark and spark-fast-tests (https://github.com/MrPowers/spark-fast-tests) to provide a good testing workflow.
quinn (https://github.com/MrPowers/quinn) and chispa (https://github.com/MrPowers/chispa) are the PySpark equivalents.
Built bebe (https://github.com/MrPowers/bebe) to expose the Spark Catalyst expressions that aren't exposed to the Scala / Python APIs.
Also build spark-sbt.g8 to create a Spark project with a single command: https://github.com/MrPowers/spark-sbt.g8

Open source contributions for a Data Engineer?
I've built popular PySpark (quinn, chispa) and Scala Spark (spark-daria, spark-fast-tests) libraries.
What are some alternatives?
flintrock - A command-line tool for launching Apache Spark clusters.
spark-fast-tests - Apache Spark testing helpers (dependency free & works with Scalatest, uTest, and MUnit)
spark-snowflake - Snowflake Data Source for Apache Spark.
spark-daria - Essential Spark extensions and helper methods ✨😲
kube-no-trouble - Easily check your clusters for use of deprecated APIs
quinn - pyspark methods to enhance developer productivity 📣 👯 🎉
transformers - 🤗 Transformers: State-of-the-art Machine Learning for Pytorch, TensorFlow, and JAX.
lowdefy - The config web stack for business apps - build internal tools, client portals, web apps, admin panels, dashboards, web sites, and CRUD apps with YAML or JSON.
null - Nullable Go types that can be marshalled/unmarshalled to/from JSON.
dagster - An orchestration platform for the development, production, and observation of data assets.
fugue - A unified interface for distributed computing. Fugue executes SQL, Python, Pandas, and Polars code on Spark, Dask and Ray without any rewrites.
