   Hi,
   
   I do serveral upsert on MOR table. When I look at the HDFS ,the are several 
pieces of delta commits
   
   ```
   .hoodie/20201122100057.deltacommit
   .hoodie/20201122100057.deltacommit.inflight
   .hoodie/20201122100057.deltacommit.requested
   .hoodie/20201122100101.deltacommit
   .hoodie/20201122100101.deltacommit.inflight
   .hoodie/20201122100101.deltacommit.requested
   ```
   
   I think 
   1.  20201122100101.deltacommit.requested means a delta commit with commitId 
`20201122100101`  is `requested to do` delta commit
   
   2. 20201122100101.deltacommit.inflight means a delta commit with commitId 
`20201122100101 is `doing` delta commit
   
   3. 20201122100101.deltacommit means a delta commit with commitId 
`20201122100101 is `done` delta commit
   
   I would ask why these 3 files are there? Does it mean every state of delta 
commit(reqeusted, inflight, and done) will be there? and old state will not be 
deleted when subsequent state is being processing?
