dbtsai opened a new pull request #27824: [SPARK-31064] [SQL] New Parquet Predicate Filter APIs with multi-part Identifier Support URL: https://github.com/apache/spark/pull/27824 ### What changes were proposed in this pull request? Parquet's org.apache.parquet.filter2.predicate.FilterApi uses dots as separators to split the column name into multi-parts of nested fields. The drawback is this causes issues when the field name contains dot. The new APIs that will be added will take array of string directly for multi-parts of nested fields, so no confusion as using dot as a separator. ### Why are the changes needed? To support nested predicate pushdown and predicate pushdown for columns containing `dots`. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Existing UTs.
