### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description The `retention` function takes as arguments a set of conditions from 1 to 32 arguments of type `UInt8` that indicate whether a certain condition was met for the event. Any condition can be specified as an argument (as in [WHERE](https://clickhouse.com/docs/en/sql-reference/statements/select/where#select-where)). The conditions, except the first, apply in pairs: the result of the second will be true if the first and second are true, of the third if the first and third are true, etc. Syntax retention(cond1, cond2, ..., cond32); Arguments `cond` — An expression that returns a `UInt8` result (1 or 0). Returned value The array of 1 or 0. 1 — Condition was met for the event. 0 — Condition wasn’t met for the event. Type: `UInt8`. ### Solution Refer to [link1](https://clickhouse.com/docs/zh/sql-reference/aggregate-functions/parametric-functions/#retention), [link2](https://github.com/apache/doris/pull/8485/files), [link3](https://github.com/apache/doris/pull/9338/files#diff-f0e1a6c2607c5fa2caa2c8f2ef12a2548dabdfa35f69dbf9a50e9c2fcb1386bf),[link4](https://github.com/ClickHouse/ClickHouse/tree/7616216f1093b09605899b225a650e64b99b9a5d/src/AggregateFunctions) for implementing retention functions, regression testing and docs. ### Are you willing to submit PR? - [X] 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.
