[jira] [Created] (HUDI-5760) Make sure DeleteBlock doesn't use Kryo for serialization to disk

Alexey Kudinkin created HUDI-5760:
-------------------------------------

             Summary: Make sure DeleteBlock doesn't use Kryo for serialization to disk
                 Key: HUDI-5760
                 URL: https://issues.apache.org/jira/browse/HUDI-5760
             Project: Apache Hudi
          Issue Type: Bug
          Components: writer-core
    Affects Versions: 1.0.0
            Reporter: Alexey Kudinkin


The problem is that serialization of the `HoodieDeleteBlock` is generated dynamically by Kryo that could change whenever any class comprising it changes.

We've been bitten by this already twice:

HUDI-5758

HUDI-4959

 

Instead, anything that is persisted on disk have to be serialized using hard-coded methods (same way HoodieDataBlock are serailized)
