joshrosen-stripe commented on issue #27089: [SPARK-30414][SQL] ParquetRowConverter optimizations: arrays, maps, plus misc. constant factors URL: https://github.com/apache/spark/pull/27089#issuecomment-571276738 @cloud-fan @HyukjinKwon @dongjoon-hyun @viirya, could you take a look at this PR which implements several small performance optimizations in `ParquetRowConverter`? These changes are aimed at improving performance when scanning very wide datasets with large numbers of columns, plus datasets with small maps and arrays. These changes are complementary but orthogonal to the changes in #26967.
