Limess opened a new issue #3854: URL: https://github.com/apache/hudi/issues/3854
**Describe the problem you faced** When benchmarking Hudi on a sample dataset we're seeing 30% lower performance using Hudi 0.9.0 vs Hudi 0.8.0 (on EMR, so technically Amazon's build of Hudi here). 0.8.0  0.9.0  We're also seeing 30% worse performance on CoW upserts of 25% of the original partition storage (50% updates, 50% inserts). 0.8.0  0.9.0  **Config** ``` "hoodie.table.name": hudi_table_name, "hoodie.datasource.write.table.type": hudi_table_type, "hoodie.parquet.max.file.size": str(int(0.5 * 1024.0 * 1024.0 * 1024.0)), "hoodie.parquet.block.size": str(int(0.5 * 1024.0 * 1024.0 * 1024.0)), "hoodie.parquet.small.file.limit": str(int(0.4 * 1024.0 * 1024.0 * 1024.0)), # one of upsert (default), insert or bulk_insert "hoodie.datasource.write.operation": hudi_write_operation, # "hoodie.datasource.write.row.writer.enable": True, "hoodie.datasource.write.recordkey.field": "_id", "hoodie.datasource.write.precombine.field": "processed_date", "hoodie.datasource.write.partitionpath.field": "story_published_date", "hoodie.datasource.write.keygenerator.class": "org.apache.hudi.keygen.TimestampBasedKeyGenerator", "hoodie.deltastreamer.keygen.timebased.timestamp.type": "DATE_STRING", "hoodie.deltastreamer.keygen.timebased.input.dateformat": "yyyy-MM-dd'T'HH:mm:ssZ,yyyy-MM-dd'T'HH:mm:ss.SSSZ", "hoodie.deltastreamer.keygen.timebased.input.dateformat.list.delimiter.regex": ",", "hoodie.deltastreamer.keygen.timebased.input.timezone": "", "hoodie.deltastreamer.keygen.timebased.output.dateformat": "yyyy-MM-dd", "hoodie.deltastreamer.keygen.timebased.output.timezone": "UTC", "hoodie.datasource.hive_sync.partition_extractor_class": "org.apache.hudi.hive.MultiPartKeysValueExtractor", "hoodie.datasource.write.hive_style_partitioning": "true", "hoodie.datasource.hive_sync.enable": "true", "hoodie.datasource.hive_sync.database": "pipeline_reprocessing_hudi_experiment", "hoodie.datasource.hive_sync.table": hudi_table_name, "hoodie.datasource.hive_sync.partition_fields": "story_published_date", "hoodie.datasource.hive_sync.jdbcurl": f"jdbc:hive2://{master_hostname}:10000", "hoodie.write.markers.type": "TIMELINE_SERVER_BASED", "hoodie.datasource.hive_sync.support_timestamp": "true", **Environment Description** EMR 6.4.0 Athena workgroup V2 (experienced on 2021/10/20) Hudi version : Tested on 0.9.0 0.8.0-amzn1 Spark version : 3.1.2 Hive version : Hive 3.1.2 Hadoop version : Amazon 3.2.1 Storage (HDFS/S3/GCS..) : S3 Running on Docker?
