cc Satish who implemented Insert Overwrite support. We have recently landed Insert Overwrite support in Hudi. Partition level deletion is a logical extension of this feature but not currently available yet. I have added a jira to track this : https://issues.apache.org/jira/browse/HUDI-1350 Meanwhile, using master branch, you can do this in 2 steps. You can generate a record for each partition you want to delete and commit the batch. This would essentially truncate the partition to 1 record. You can then issue a hard delete on that record. By keeping cleaner retention to 1, you can essentially cleanup the files in the directory. Satish - Can you chime in and see if this makes sense and if you are seeing any issues with this ?

I have a COW table which has sub partition columns Date/Hour . For some of the use case , I need to totally remove free petitions (removing few hours alone) . Hudi maintains metadata info. Manually removing folders as well as in hive megastore , may mess up hudi metadata. What is the best way to do this? Thanks, Selva
