Hi folks, Firstly, thanks Jarek for putting together such a thorough and well-thought-out proposal.
I am very much in support of the multi-tenancy proposal. Having discussed this with over 30 customers (AWS and non-AWS), there's a clear desire to shift focus from the complex management of multiple Airflow environments to enhancing their capabilities, such as enabling data quality checks and lineage. This proposal is a significant step towards achieving that goal. Acknowledging that not every Airflow user has enough time to thoroughly review the AIP, I have drafted a user scenario that encapsulates what's possible with the implementation of multi-tenancy support: ---- Scenario: Multi-Tenancy in Apache Airflow at [Rocket] ---- [Rocket], a leading [mobile gaming platform], has adeptly structured its cloud operations using Apache Airflow to provide an efficient and secure multi-tenant environment for orchestrating their complex workflows. This approach caters to the diverse needs of their three main user groups: the Data Engineering team, the Data Science team, and the Data Analytics team. All teams share basic Airflow components like the Scheduler and Webserver, providing centralized management with shared cost. Each team has its own distinct tenant cluster, offering self-sufficiency, flexibility, and isolation. The Data Engineering team builds ETL/ELT pipelines and produces user profile, telemetry, and marketing data. The Analytics team works with marketing data and user information to build comprehensive dashboards. The Data Science team uses Kubernetes as their execution environment for heavy-duty machine learning tasks, producing a churn prediction dataset. Members of each team can only see and work with their own workflows. However, Data engineers are granted access to all tenants, enabling them to assist with DAG troubleshooting and optimization across all teams. Upon logging in, users are presented with a tenant-specific view, displaying only the relevant DAGs and artifacts. For those with multi-tenant access, seamless navigation between different tenant views is available without the need for re-authentication. This setup lets each team work independently with their own tools and data, while also getting help from data engineers when needed. It's secure, efficient, and user-friendly.

For those interested in diving deeper into the details, the AIP is available here - https://cwiki.apache.org/confluence/display/AIRFLOW/AIP-67+Multi-tenant+deployment+of+Airflow+components Thanks Shubham Product Manager - Amazon MWAA From: Jarek Potiuk <ja...@potiuk.com> Reply-To: "us...@airflow.apache.org" <us...@airflow.apache.org> Date: Monday, March 11, 2024 at 4:05 PM To: "dev@airflow.apache.org" <dev@airflow.apache.org>, "us...@airflow.apache.org" <us...@airflow.apache.org> Subject: RE: [EXTERNAL] [COURRIEL EXTERNE] [DISCUSS] DRAFT AIP-67 Multi-tenant deployment of Airflow components CAUTION: This email originated from outside of the organization.

I have iterated and already got a LOT of comments from a LOT of people (Thanks everyone who spent time on it ). I'd say the document is out of draft already, it very much describes the idea of multi-tenancy that I hope we will be voting on some time in the future. Taking into account that ~ 30% of people in our survey said they want "mutl-tenancy" - what I am REALLY interested in is to get honest feedback about the proposal. Manly: *"Is this the multi-tenancy you were looking for?" Or were you looking for different droids (err, tenants) maybe?. I do not want to exercise my Jedi skills to influence your opinion, that's why the document is there (and some people say it's nice, readable and pretty complete) so that you can judge yourself and give feedback. The document is here: https://cwiki.apache.org/confluence/display/AIRFLOW/AIP-67+Multi-tenant+deployment+of+Airflow+components Feel free to comment here, or in the document. I would love to hear more voices, and have some ideas what to do next to validate the idea, so please - engage for now - but also expect some follow-ups. J.

Seems that it's an AIP time :D I've just published a Draft of AIP-67: Multi-tenant deployment of Airflow components https://cwiki.apache.org/confluence/display/AIRFLOW/%5BDRAFT%5D+AIP-67+Multi-tenant+deployment+of+Airflow+components This AIP is a bit lighter in detail than the others you could see from Jed , Nikolas and Maciej. This is really a DRAFT / High Level idea of Multi-Tenancy that could be implemented as the follow-up after previous steps of Multi-Tenancy implemented (or being implemented) right now. I decided to - rather than describe all the details now - focus on the concept of Multitenancy that I wanted to propose. Most of all explaining the concept, comparing it to current ways of achieving some forms of multi-tenancy and showing benefits and drawbacks of the solution and connected costs (i.e. what complexity we need to add to achieve it). When thinking about Multi-tenancy, I realized few things: * everyone might understand multi-tenancy differently * some forms of multi-tenancy are achievable even today * but - most of all - I started to question myself "Is this what we can do, enough for some, sufficiently numerous groups of users to call it a useful feature for them". So before we get into more details - my aim is to make sure we are all at the same page on what we CAN do as a multi-tenancy, and eventually to decide whether we SHOULD do it. Have fun. Bring in comments and feedback. More about all the currently active AIPs at today's Town Hall BTW. Do you think it's a surprise that 5 AIPS were announced just before the Town Hall? I think not :D J.
