[I] [Enhancement] Add optional argument to APPROX_COUNT_DISTINCT to tune the error rate [doris]
jpohanka opened a new issue, #26413:
URL: https://github.com/apache/doris/issues/26413
### 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
Many query engines and databases implement the approximate count distinct with an optional parameter to calibrate the resulting accuracy of the function.
Examples:
- Trino : https://trino.io/docs/current/functions/aggregate.html?highlight=approx_distinct#approx_distinct
- Pinot: https://docs.pinot.apache.org/configuration-reference/functions/distinctcounthll
This could be also added to Doris's APPROX_COUNT_DISTINCT function as an optional 'error rate' parameter.
### Solution
