@bkietz before I rebase these changes on top of https://github.com/apache/arrow/pull/43761, do you have any thoughts on the high level approach? Specifically - Any concerns with using the `SimplificationContext` unordered map to defer binding the simplified `is_in` exprs until all inequalities have been processed? - Any thoughts on how to use `ArrayStatistics` for this optimization? It appears that the statistics class was added, but they aren't computed anywhere. Also, transparently updating `ArrayStatistics::is_sorted` across calls to `SortIndices` and `Take` doesn't seem straightforward. Were you thinking that `ArrayStatistics::is_sorted` would be manually set by the caller? - It sounds like we're ok with storing the memoized sorted and unique value set in the kernel state, even though it's not used by the kernel? -- This is an automated message from the Apache Git Service.
