sandugood opened a new pull request, #1650:
URL: https://github.com/apache/datafusion-ballista/pull/1650
# Which issue does this PR close?
Closes #1627.
# Rationale for this change
Add additional optional query parameters to the Scheduler's REST API to get
data about the jobs.
# What changes are included in this PR?
1. Added JobQueryParams struct for optional query parameters construction
with two fields: include_logical and tree_rendered
2. Based on optional parameters a JSON response is formed:
- `include_logical` is true by default, but can be configured to be excluded
from the response. Extracted by the name it is responsible for returning
`logical_plan` to the user
- `tree_rendered` is the query parameter that controls how `physical_plan`
is rendered. If `tree_rendered` is set to `false` then it is rendered as
`DisplayableExecutionPlan::new(job.physical_plan().as_ref()).indent(false)`,
otherwise
`displayable(job.physical_plan().as_ref()).tree_render().to_string()`, which
can be easily rendered on the user side
```
