### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description At present, Doris's disk spilling mechanism works by splitting a hash table into a fixed number of partitions (e.g., 16) for disk writing, with no recursion implemented. Therefore, when memory is truly insufficient, the actual maximum memory footprint for disk spilling is only 15/16 of the total. We need to implement a recursive strategy that allows further recursive partitioning within each 1/16 partition. The goal is to run all TPC-DS 1TB queries with just 10GB of memory. ### Solution _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
