### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Motivation Spark currently builds sorted indexes for different Paimon partitions serially, limiting index-building efficiency. Parallel index building across partitions should be supported. ### Solution Following Flink's approach, assign each partition build task an ID, merge all tasks, and repartition and sort them together for parallel execution. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
