THANK YOU!

@oznur-synnada I wonder if you might be willing to add some additional links to this page.

For example there are some links on the weekly summaries I write that maybe could be mined, such as

• Jan 1, 2025: This week(s) in DataFusion #13970 (comment)
• Feb 4, 2025: This week(s) in DataFusion #14491

[oznur-synnada]

Sure, @alamb I'll dive in and come up with a list of links that could be added to this page.

Thank you !

Hi @alamb here's what I think could be added. I tried to keep this list confined to sources specific to DataFusion i.e. without mentions or discussions of other projects. I'm not sure about some of these so I'd appreciate your input:

• Weekly Call for the Community - I don't know if it'd be ok to share this openly on the website, though it's open to anyone.
• Recording of the Amsterdam event
• Recap of the Amsterdam event
• DataFusion 44 released - I saw that the releases on the web page aren’t up to date, though I couldn’t find the blog post for this one
• DataFusion Python 44 released - same situation.
