coffee34 opened a new issue, #8132:
URL: https://github.com/apache/hudi/issues/8132
**Describe the problem you faced**
I encountered data loss in hudi mor table. After compaction, a base file
became smaller and lost data. The issue occurred on 2023-01-10 and I am only
able to access archived commits.(The parquet and log files for those instants
have already been deleted.) I have uploaded all the commits. Here is the
timeline of the basefile: **8fb29db6-81da-4455-a08d-ba3e7ee36856-0**, it shows
that its size was 116M until L23. However, it became 66M after compaction and
lost 890k records.
