----------------------------------
Summary: Incorrect keyby field would cause serious data skew
Key: HUDI-1918
URL: https://issues.apache.org/jira/browse/HUDI-1918
Project: Apache Hudi
Issue Type: Bug
Components: Flink Integration
Reporter: zhangminglei
Assignee: zhangminglei
The code
(https://github.com/apache/hudi/blob/master/hudi-flink/src/main/java/org/apache/hudi/streamer/HoodieFlinkStreamer.java#L92),
in the actual data warehouse, partition path is most based on log_date or
log_hour, so keyBy (HoodieRecord: :getPartitionPath) that would cause serious
data skew.
we can actually shuffle data by record key here, just like the pipeline in
HoodieTableSink.
