### What changes were proposed in this pull request? This PR renames the SQL config key `spark.sql.optimizer.mergeSubplans.symmetricFilterPropagation.enabled` to `spark.sql.optimizer.mergeSubplans.filterPropagation.symmetricFilterPropagation.enabled`. ### Why are the changes needed? To follow the Apache Spark configuration namespace rule. The new key better reflects the configuration hierarchy. `spark.sql.optimizer.mergeSubplans.filterPropagation.enabled` is the parent gate for filter propagation in `MergeSubplans`, and the symmetric variant is a sub-feature of it. Nesting the symmetric flag under `filterPropagation.*` makes that relationship explicit, and groups related options together when listed alphabetically. The previous key `mergeSubplans.symmetricFilterPropagation.enabled` placed the two sibling options at different levels of the namespace, which obscured the dependency (the symmetric flag has no effect when filter propagation is disabled, as documented in the config `doc`). This config was added in 4.2.0 and has not been released yet, so no backwards-compat alias is required. ### Does this PR introduce _any_ user-facing change? No. The config has not been released yet (introduced for 4.2.0). ### How was this patch tested? Pass the CIs. - `build/sbt 'catalyst/testOnly *MergeSubplansSuite'` - `build/sbt 'sql/testOnly *PlanMergeSuite'` ### Was this patch authored or co-authored using generative AI tooling?
