[jira] [Created] (IGNITE-13752) Schema evolution converters.

Andrey Mashenkov created IGNITE-13752:
-----------------------------------------

             Summary: Schema evolution converters.
                 Key: IGNITE-13752
                 URL: https://issues.apache.org/jira/browse/IGNITE-13752
             Project: Ignite
          Issue Type: Improvement
            Reporter: Andrey Mashenkov


With "live" schema it should be able to deserialize tuples of old-version to a new classes regarding schema change history.

Startpoint is to investigate if we could generate converter source->target schema version and them apply changes to data: e.g. column add/remove, default value change.
