> Truncate long node labels in SQL plan visualization
> ---------------------------------------------------
>
> Key: SPARK-56331
> URL: https://issues.apache.org/jira/browse/SPARK-56331
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.2.0
> Reporter: Kent Yao
> Assignee: Kent Yao
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.2.0
>
>
> When SQL plan node names are long (e.g., scan nodes with fully-qualified
> catalog.schema.table paths from custom catalogs), the plan visualization
> graph becomes excessively wide and hard to read.
> Proposed fix: truncate node labels to 36 characters using middle-ellipsis
> (keep operator prefix + table name, truncate catalog/schema path). Full text
> remains available in the tooltip and side panel.
> Example:
> Before: ScanTransformer parquet spark_catalog.longschemaname.catalog_sales
> (60+ chars)
> After: ScanTransformer pa...catalog_sales (36 chars)
> Implementation: in spark-sql-viz.js, apply middle-truncation when generating
> DOT graph labels.
