uros-b opened a new pull request, #57846: URL: https://github.com/apache/spark/pull/57846
### What changes were proposed in this pull request? Replaces a stale sentence in the caching section of `docs/sql-performance-tuning.md`. The old text told users to call `spark.catalog.listCachedTables()`; the new text points to `spark.catalog.isCached`, the `Dataset.storageLevel` property, and the web UI Storage tab. ### Why are the changes needed? `spark.catalog.listCachedTables()` no longer exists. It was removed by the SPARK-56221 followup (`a3930d31665`) along with the `SHOW CACHED TABLES` command. That commit edited this sentence to drop the SQL command but left the `listCachedTables()` call in place, so the guide currently points at a method that cannot be called. This is the only remaining reference to the removed API in the repository. Each replacement is a documented API: `Catalog.isCached` (`sql/api/.../catalog/Catalog.scala`), `Dataset.storageLevel`, whose implementation returns `StorageLevel.NONE` when the data is not cached, and the Storage tab, which `docs/web-ui.md` describes as showing "the storage levels, sizes and partitions of all RDDs" and notes does not list a relation "before they are materialized". The Storage tab also covers data cached via `Dataset.cache()` without a name, which is what the removed API could not report. ### Does this PR introduce _any_ user-facing change? No, other than the corrected documentation. ### How was this patch tested? Documentation only. The `#storage-tab` anchor matches the `## Storage Tab` heading in `docs/web-ui.md`, and the link style matches the existing `[SQL UI](web-ui.html#sql-tab)` reference in this same file. ### Was this patch authored or co-authored using generative AI tooling?
