My (personal) North ⭐ : 1000 projects are built using DataFusion 📈
It would be great for other contributors to DataFusion who plan non trivial work could try to make them visible somehow as well 🙏 (feel free to copy / modify the format)
My Highlights from Last Week
LogicalPlan
during OptimizerPasses #9637 (and [this pr](Stop copying LogicalPlan and Exprs inTypeCoercion
(10% faster planning) #10356 gets another 10% faster)). Thanks @dmitrybugakov, @emgeee, @rohitrastogi,StringViewArray
support is coming (this pr 🙏 @RinChanNOWWW and [this pr](https://github.com/apache/arrow-rs/pull/5707] from @ClSlaid ).AggregateFunction
Interface (remove built in list ofAggregateFunction
s), improve the system #8708 forward (e.g. this pr)0.46.0

arrow-rs#5374 (I am struggling to find time, but we are making progress, slowly)Algorithm for (my) prioritizing PR reviews
Note there are many committers who can and do review and merge PRs, so this is not the priorities of the project as a whole, just the approximate algorithm I use to prioritize my own time.
Priority:
The top strategically important projects in my head are:
Thus, if you are interested in contributing to DataFusion and are interested in a fast turn around time I would recommend looking into bug fixes / test improvements / documentation or the projects named above.
If you propose adding new functionality, especially if the PR is large/complex and not connected to a wider need, the review cycle will likely be longer. You can make it a shorter cycle by looking at the comments on other recent PRs and following the same model (e.g. ensure there are tests in sqllogictest for example, the CI passes, includes documentation, etc)
