ABN tackled this through their Data Integration Access Layer - similar to a service bus.They are using that centralized layer - called DIAL - to help teams manage integrations that are both consistently running and on-the-fly. It helps monitor for duplication of work instead of reuse.If Mahmoud could do it again, he'd focus on enabling easy data integration earlier in their journey to encourage more data consumption. Cross domain and cross data product consumption is highly valuable.The industry needs to develop more and better standards to enable easy data integration.Data mesh and similar decentralized data approaches cannot fully decentralize everything. Look for places to centralize offerings in a platform or platform-like approach that can be leveraged by decentralized teams.Most current data technology licensing models aren't well designed for or suited to doing decentralized data - it's easy to pay a lot if you aren't careful - or even if you are careful!A tough but necessary mentality shift is not thinking about being "done" once data is delivered. That's data projects, not data as a product.Try to keep as much work as possible within the domain boundary when doing data work. Of course, cross-domain communication is key but try to limit the actual work dependencies on other domains if possible.A data marketplace enables organizations to more easily create a standardized experience across data products and make data discovery much easier. You don't necessarily have to tie your cost allocation models to the marketplace concept.Sharing what analytical queries/data integration "recipes" people are using has been important for ABN. It drives insights across boundaries and also creates a lower bar to interesting tangential insight...

Interviews with data mesh practitioners, deep dives/how-tos, anti-patterns, panels, chats (not debates) with skeptics, "mesh musings", and so much more. Host Scott Hirleman (founder of the Data Mesh Learning Community) shares his learnings - and those of the broader data community - from over a year of deep diving into data mesh. Each episode contains a BLUF - bottom line, up front - so you can quickly absorb a few key takeaways and also decide if an episode will be useful to you - nothing worse than listening for 20+ minutes before figuring out if a podcast episode is going to be interesting and/or incremental ;) Hoping to provide quality transcripts in the future - if you want to help, please reach out! Data Mesh Radio is also looking for guests to share their experience with data mesh! Even if that experience is 'I am confused, let's chat about' some specific topic. Yes, that could be you! You can check out our guest and feedback FAQ, including how to submit your name to be a guest and how to submit feedback - including anonymously if you want - here: https://docs.google.com/document/d/1dDdb1mEhmcYqx3xYAvPuM1FZMuGiCszyY9x8X250KuQ/edit?usp=sharing Data Mesh Radio is committed to diversity and inclusion. This includes in our guests and guest hosts. If you are part of a minoritized group, please see this as an open invitation to being a guest, so please hit the link above. If you are looking for additional useful information on data mesh, we recommend the community resources from Data Mesh Learning. All are vendor independent. https://datameshlearning.com/community/ You should also follow Zhamak Dehghani (founder of the data mesh concept); she posts a lot of great things on LinkedIn and has a wonderful data mesh book through O'Reilly. Plus, she's just a nice person: https://www.linkedin.com/in/zhamak-dehghani/detail/recent-activity/shares/ Data Mesh Radio is provided as a free community resource by DataStax. If you need a database that is easy to scale - read: serverless - but also easy to develop for - many APIs including gRPC, REST, JSON, GraphQL, etc. all of which are OSS under the Stargate project - check out DataStax's AstraDB service :) Built on Apache Cassandra, AstraDB is very performant and oh yeah, is also multi-region/multi-cloud so you can focus on scaling your company, not your database.
