### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Motivation Users often store complex data such as `user1, user2, user3` as simple string rather then complex date type (map,array). When aggregating these fields, there is currently no support for deduplication `set.add`. ### Solution Add a `distinct` option support to FieldListAgg? ### Anything else? This approach works fine for `user1,user2,user3`, but it's insufficient for kv-string deduplication (k1=v1;k2=v2). I'm not sure whether to handle this with string manipulation or a map-merge aggregation approach. ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
