-----------------------------------
Labels: pull-request-available (was: )
> Use consistent colName interpolation in CatalogColumnStat
> ---------------------------------------------------------
>
> Key: SPARK-58760
> URL: https://issues.apache.org/jira/browse/SPARK-58760
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.3.0
> Reporter: Uroš Bojanić
> Priority: Major
> Labels: pull-request-available
>
> CatalogColumnStat.toMap and fromMap build the table-property keys for column
> statistics by interpolating the column name and a key constant, and they mix
> ${colName} with the bare $colName for the same value, including on adjacent
> lines (the histogram key already uses $colName).
> This unbraces the 14 remaining ${colName} occurrences to $colName, matching
> the file's own dominant style. The qualified selects such as
> ${CatalogColumnStat.KEY_VERSION} keep their braces, since dropping those
> would interpolate the object and append the member name as literal text.
> Behavior is unchanged: in every case colName is a simple parameter
> immediately followed by a dot, so $colName. parses identically to ${colName}.
> and the generated property keys are byte-for-byte the same, preserving
> metadata compatibility.
