fatmanverse opened a new issue, #18425:
URL: https://github.com/apache/dolphinscheduler/issues/18425
### Search before asking
- [x] I had searched in the issues and found no similar documentation
request or DSIP.
### Description
The built-in parameter documentation lists the available `system.*`
variables and some time expressions, but it does not explain how each parameter
behaves across scheduled, complement, and manual runs. It also lacks complete
usage examples for the time-expression functions and does not describe how
named parameters `${...}` and time expressions `$[...]` are resolved when they
are combined.
The documentation should:
- Explain the value and usage of every current `system.*` built-in parameter.
- Clarify the benchmark time used by `$[...]` expressions.
- Document date arithmetic, calendar boundary functions, and
`timestamp(...)`.
- Describe the resolution order for `${...}` and `$[...]`.
- Add Shell, SQL, custom parameter, and downstream parameter examples.
- Keep the English and Chinese documentation and navigation in sync.
This is an incremental documentation improvement and does not change public
interfaces or runtime behavior.
