Subject Re: [ANNOUNCE] Apache Phoenix 4.15.0 released
Date Sat, 21 Dec 2019 20:39:05 GMT
One thing I would like to suggest is a change to the project compatibility policy for upgrade/downgrade
to support the following:

Mixed client/server versions one minor release up or back. Going forward. So in the future
eg client={ 4.14, 4.15, 4.16 } <-> server={ 4.14, 4.15, 4.16 }. This will allow for
seamless rolling upgrades with rollback in all common scenarios. 

Then, consider an exception for some combinations of 4.15 and 5.1? I have tested this and
these versions are data compatible (create data with 1.5/4.14, upgrade to 2.2/5.1) and at
the HBase level the wire compatibility between 1 and 2 is good enough for normal client operations.
If the version check didn’t throw an exception I wonder if there would be any issue. 

For your consideration.
