Hamilton is a lightweight in-process framework to define, execute, and observe directed acyclic graphs (DAGs) that express data transformations. In Hamilton, one can express complex DAGs of transformations, e.g. from dataframe transformations (using pandas, polars, PySpark), machine learning pipelines, through to regular software engineering API request and LLM API based workflows. Observability hooks are built into the framework. The Hamilton UI is a self-hostable service to capture observability output from workflow runs. Hamilton has been incubating since 2025-04-12. ### Three most important unfinished issues to address before graduating: 1. Finish check list to be able to make a release 2. Start releasing 3. Enable more contributors ### Are there any issues that the IPMC or ASF Board need to be aware of? ### How has the community developed since the last report? Flat. Slack continues to trickle in. Non PPMC users contributed some code. ### How has the project developed since the last report? 1. We have many merged features that haven't been released. 2. Some PRs were merged for licensing etc. Docs were updated. 3. But still more work needed for first release. ### How would you assess the podling's maturity? Please feel free to add your own commentary. - [X] Initial setup - [ ] Working towards first release <== here - [ ] Community building - [ ] Nearing graduation - [ ] Other: ### Date of last release: N/A ### When were the last committers or PPMC members elected? April 2025 ### Have your mentors been helpful and responsive? Time for the committers has been an issue this summer to get through the checklist required to release under Apache. ### Is the PPMC managing the podling's brand / trademarks? I think so. No issues thus far. ### Signed-off-by: - [ ] (hamilton) Kevin Ratnasekera Comments: - [X] (hamilton) Ayush Saxena Comments: - [X] (hamilton) PJ Fanning Comments: Podling name is approved. We got it approved before setting up ASF resources. ### IPMC/Shepherd notes:
