dongjoon-hyun opened a new pull request, #550:
URL: https://github.com/apache/spark-connect-swift/pull/550
### What changes were proposed in this pull request?
This PR aims to pass the plan ID in `DataFrame.colRegex`, like PySpark, now
that `DataFrame` relations have plan IDs (SPARK-59414).
- Set `planID` of `UnresolvedRegex` in `colRegex`.
- Update the doc comment. The server uses the plan ID only for a column name
without backticks, which is resolved as a regular column reference bound to the
`DataFrame` like `col(_:)`. A regex enclosed in backticks is still not bound to
the `DataFrame`.
### Why are the changes needed?
When SPARK-59399 added `colRegex`, this client had no plan IDs. As a result,
a column name without backticks could not be disambiguated when both sides of a
join had it.
```swift
let df = try await spark.range(3)
let df1 = await df.filter("id > 0")
let df2 = await df.select("id")
let joined = await df1.join(df2, joinExprs: df1.colRegex("id") ==
df2.colRegex("id"))
```
### Does this PR introduce _any_ user-facing change?
No. `colRegex` is not released yet.
### How was this patch tested?
Pass the CIs with the newly added test case.
### Was this patch authored or co-authored using generative AI tooling?
