XiaoHongbo-Hope opened a new pull request, #9242:
URL: https://github.com/apache/paimon/pull/9242

   PyPaimon currently sorts Data Evolution manifest entries by sequence before 
grouping overlapping row-id ranges. Java preserves the manifest input order 
within each group, and paimon-rust follows the same contract in 
apache/paimon-rust#717.
   
   This removes the planner-only pre-sort and preserves manifest order within 
each row-id group. The reader still applies its own ordering for merge 
execution.
   
   Tests:
   - data evolution split, stats, deletion-vector, and chunk-shuffle tests: 95 
passed
   - related Data Evolution tests: 71 passed
