Oh well. For Maps, you might want to look at the mapping of Spark's MapType to a Parquet Schema here: https://github.com/apache/datafusion-comet/blob/320ce55eec9f4c846ad7a68bb69c182ae1fcd3ce/common/src/main/scala/org/apache/spark/sql/comet/parquet/CometSparkToParquetSchemaConverter.scala#L254 https://github.com/apache/datafusion-comet/blob/320ce55eec9f4c846ad7a68bb69c182ae1fcd3ce/common/src/main/scala/org/apache/spark/sql/comet/parquet/CometSparkToParquetSchemaConverter.scala#L287 Essentially a Map type is a repeated group of key and value fields. Note however that both key and value can themselves be complex types as in this test file: https://github.com/apache/datafusion-comet/blob/320ce55eec9f4c846ad7a68bb69c182ae1fcd3ce/spark/src/test/scala/org/apache/spark/sql/CometTestBase.scala#L719 -- This is an automated message from the Apache Git Service.
