Hello Sir. I was just trying to reference the relevant mailing list links when submitting [HIVE-28681] Default to disable hive.optimize.reducededuplication - ASF JIRA. (I pin old historical emails by replying to them and then copy their web links.) However, whether we should default to disabling reducededuplication is a matter that needs to be discussed; perhaps it should be enabled by default, but the default parameter settings related to reducededuplication are not quite appropriate.
Furthermore, since the authors of the article are Seonggon Namgung and Sungwoo Park, I believe we should seek their opinions. Seonggon Namgung & Sungwoo Park, what do you think? -lisoda 在 2024-12-30 04:44:04，"Ayush Saxena" <ayush...@gmail.com> 写道： If it is related to Hive we can get it posted on the Hive’s Twitter page as well, If you say so & share us what you want to write along with the link to the blog https://x.com/apachehive -Ayush On 28 Dec 2024, at 4:43 PM, lisoda <lis...@yeah.net> wrote: see again ---- Replied Message ---- | From | lisoda<lis...@yeah.net> | | Date | 12/24/2023 00:28 | | To | user<user@hive.apache.org> | | Cc | | | Subject | Re: Blog article 'Performance Tuning for Single-table Queries' | ---- Replied Message ---- | From | Sungwoo Park<glap...@gmail.com> | | Date | 12/24/2023 00:06 | | To | user@hive.apache.org | | Cc | | | Subject | Blog article 'Performance Tuning for Single-table Queries' | Hello Hive users, I have published a new blog article 'Performance Tuning for Single-table Queries'. It shows how to change configuration parameters of Hive and Tez in order to make simple queries run faster than Spark. Although it uses Hive on MR3, the technique equally applies to Hive on Tez and Hive-LLAP. https://www.datamonad.com/post/2023-12-23-optimize-bi-1.8/ Hope you find it useful. Cheers, --- Sungwoo
