liviazhu opened a new pull request, #58183: URL: https://github.com/apache/spark/pull/58183
### What changes were proposed in this pull request? Document that users should set `spark.sql.streaming.stateStore.rocksdb.maxOpenFiles` to a positive value when a streaming query fails to open RocksDB with `Too many open files`. JIRA: https://issues.apache.org/jira/browse/SPARK-58925 ### Why are the changes needed? The existing documentation explains the open-file cache behavior but does not tell users how to configure RocksDB after reaching the operating system's open file limit. ### Does this PR introduce _any_ user-facing change? No. This is a documentation-only update. ### How was this patch tested? Validated with `git diff --check`. No runtime tests are applicable to this documentation-only change. ### Was this patch authored or co-authored using generative AI tooling?
