[jira] [Created] (HUDI-2268) Upgrade hoodie table for 0.9.0

sivabalan narayanan created HUDI-2268:
-----------------------------------------

             Summary: Upgrade hoodie table for 0.9.0
                 Key: HUDI-2268
                 URL: https://issues.apache.org/jira/browse/HUDI-2268
             Project: Apache Hudi
          Issue Type: Improvement
          Components: Usability
            Reporter: sivabalan narayanan
             Fix For: 0.9.0


Wrt upgrading/downgrading hoodie.properties, here is what we can go. 

Add a new table version, 2. 

Add an upgrade step:

before every write operation. 

     Check if existing hoodie.props is in an older version. If yes, perform upgrade step to version2 (either from 0 to 2 or from 1 to 2). This essentially means that we need to add new properties pertaining to sql dml to hoodie.properties. 

 

Downgrade step: 

hoodie.properties will have some additional properties. Should not cause any harm. All we need to do is to downgrade the table version to target version and not touch any of the props.
