### 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 Now the window_funnel function has only one mode that is 'default', hope Doris can support other modes: 1. mode = 0 means DEFAULT 2. mode = 1 means DEDUPLICATION. The filtered event chain cannot have duplicate events. Suppose the array parameter is [event1='A', event2='B', event3='C', event4='D'], and the original event chain is "A-B-C-B-D". Since event B repeats, the filtered event chain can only be "A-B-C". 3. mode = 2 means FIXED. The filtered event chain cannot have jumping events. Assuming that the array parameters remain unchanged as above, the original event chain is "A-B-D-C". Since event D jumps, the filtered event chain can only be "A-B". 4. mode = 4 means INCREASE. In the filtered event chain, the timestamps of consecutive events must be strictly increasing. ### 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.
