Maintainers are most responsive around 07:00 UTC (07:00 UTC in your timezone). Recommended submission window is Wednesday - Friday from 04:00 to 08:00 UTC (04:00 - 08:00 UTC local).
Maintainer Strategy: Maintainer Sweet Spot: PRs under 150 lines merge in ~16 hours (96% approval). Large PRs (>500 lines) take ~115 hours (40% approval). Keep your diff compact for rapid review.
Motivation Sedona ships four H3 functions (ST_H3CellIDs, ST_H3CellDistance, ST_H3KRing, ST_H3ToGeom) but none of the H3 hierarchy functions. Parent/child hiearchy functions and cell compactions are rommon H3 workflows that aren't currently expressible in Sedona SQL. The h3 library Sedona already depends on exposes all of these on the existing H3Utils.h3 instance, so no new dependency is needed. Related: #2329, #914, #1752. Proposed functions Function H3 method Returns ST_H3ToParent(cell, resolution) cellToParent long ST_H3ToChildren(cell, resolution) cellToChildren array ST_H3ToCenterChild(cell, resolution) cellToCenterChild long ST_H3Compact(cells) compactCells array ST_H3Uncompact(cells, resolution) uncompactCells array Rollout I'd like to land these incrementally, one function per PR, starting with ST_H3ToParent.

We call it Airflow Breeze as It's a Breeze to contribute to Airflow. I have worked with Apache Airflow, the Breeze Docker environment and the pre-commit / prek hooks system. https://github.com/apache/airflow/blob/main/dev/breeze/doc/README.rst refs #2729 refs #2202 Gemini is AI and can make mistakes so double check it What is Breeze Apache Airflow Breeze is a Python-based CLI development environment designed to streamline workflows for project contributors and maintainers. It eliminates the need to manually manage complex Docker topologies and conflicting Python dependencies by encapsulating them into a single platform. By utilizing the exact same Docker images and configuration matrices locally as the GitHub Actions CI pipelines, it ensures absolute environment parity. This structural consistency prevents environment drift and drastically reduces wasted CI compute cycles during pull request reviews. Developers can instantly swap runtime environments, including various Python version
Original failed run seen here: https://github.com/apache/sedona/actions/runs/22992869182/job/66757741342 This hook is here: sedona/.pre-commit-config.yaml Line 510 in 3ac6397 - repo: https://github.com/rhysd/actionlint So maybe we can remove some ignores and clean up the code ??
We already have two ideas linked below similar to this refs #2436 refs #2428 While many Apache Software Foundation (ASF) projects stick to a classic, text-heavy "Apache Way" aesthetic, a new generation of Top-Level Projects (TLPs) has embraced modern web design. These projects often feature sleek UI, clear branding, and dedicated "Community" or "Team" pages with high-quality avatars and contributor profiles. https://echarts.apache.org/en/committers.html https://apisix.apache.org/team/ https://airflow.apache.org/community/#project-management-committee I think avatars should be stored with the site so PMC and Committers can choose their avatar if needed.
