Thanks @berkaysynnada In general I suggest emphasizing things that many users of the crate will see / appreciate and mentioning, but not too deeply, things that developers of the crate care more about I also suggest that until we enable a feature by default we should not make a big deal about it. The rationale is that most users won't use it until it is on by default, and we can make a big deal about it when it is available I suggest emphasizing: - https://github.com/apache/datafusion/pull/14579 - GSOC for sure I would also mention that we are working on statistics / monotonicity, but until there is something major we can point at that is user facing (e.g. an important SQL query that now goes faster with the monotonicity changes) I probably wouldn't emphasize them I think these ones are worth mentioning but don't make a huge deal: - https://github.com/apache/datafusion/pull/14224 These ones are in progress so I would suggest we wait t: - https://github.com/apache/datafusion/pull/13664 - https://github.com/apache/datafusion/pull/14699 I would suggesting highlighting the performance improvements - perf: Improve median with no grouping by 2X https://github.com/apache/datafusion/pull/14399 (2010YOUY01) - Improve performance 10%-100% in FIRST_VALUE / LAST_VALUE by not sort rows in FirstValueAccumulator https://github.com/apache/datafusion/pull/14402 (blaginin) - Speed up uuid UDF (40x faster) https://github.com/apache/datafusion/pull/14675 (simonvandel) - perf: Drop RowConverter from GroupOrderingPartial https://github.com/apache/datafusion/pull/14566 (ctsk) Speedup to_hex (~2x faster) https://github.com/apache/datafusion/pull/14686 (simonvandel) - Implement predicate pruning for not like expressions https://github.com/apache/datafusion/pull/14567 (UBarney) - Speed up chr UDF (~4x faster) https://github.com/apache/datafusion/pull/14700 (simonvandel) Also I suggest pointing people at the new upgrade guide: https://github.com/apache/datafusion/blob/main/docs/source/library-user-guide/upgrading.md#datafusion-4600 And maybe we can refer people to https://github.com/apache/datafusion/blob/main/dev/changelog/46.0.0.md for more details -- This is an automated message from the Apache Git Service.
