sivabalan narayanan updated HUDI-9097:
--------------------------------------
    Description: 
This ticket tracks the design of such b/w compatible support. 

Requirement is covered in the parent ticket. 

Here is the impl Jira https://issues.apache.org/jira/browse/HUDI-9013 

  was:
This ticket tracks the design of such b/w compatible support. 

Reqs: 
 * Able to write using tbl version 6 with mdt enabled.
 * 1.0 binary able to read any 0.x table w/ mdt enabled. 
 * Seamless upgrade to 1.0 w/o nuking entire mdt.
 * Also provide a downgrade path w/o nuking entire MDT if feasible. 

Expectations:
 * All storage changes should be accounted for
 * In memory computation should be retained as much as possible to align w/ 0.x 
behavior. 
 * Its ok to force full compaction in MDT during upgrade. Anyways, we only do 
snapshot read on MDT. So, once compacted, we should not have any issues w/ MDT. 
no one will ever read older file slices from MDT.
