Research direction

The issue lists release tasks: creating a branch-0.12 branch, updating the version and changelog, testing with DataFusion Ballista and DataFusion Distributed, running a voting thread, and publishing to crates.io. Start by identifying current release blockers and the work needed for the listed checks; the issue gives no file or test entry points. Done means completing the agreed release steps, publishing version 0.12.0, and creating the follow-up ticket and blog post.

Description

I copied the structure from DataFusion, but for now we can mostly just use this to discuss things we want to see in the first release, and any current blockers. I think the crate name/ownership has now been sorted.

Steps:
  • Create a branch-0.12 branch
  • Update version and changelog
  • Test with DataFusion Ballista
  • Test with DataFusion Distributed
  • Voting Thread
  • Publish to crates.io
  • Create ticket for next release
  • Create blog post

Features to mention in the blog (if they make it)
