### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Motivation In many scenarios, such as UV computing and user profile analysis, traditional approaches typically rely on count-distinct operations, which are resource-intensive. A more efficient alternative is to use RoaringBitmap, which can significantly reduce computing resource consumption. The application of RoaringBitmap depends on the storage engine's support for auto-increment columns, which can map any user-defined UID into an INT32/INT64 space. ### Solution Support auto-increment columns through a server-side serial allocation mechanism. We don't need to ensure global ordering, just bucket-level ordering. ### Anything else? _No response_ ### Willingness to contribute - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
