C. Scott Andreas updated CASSANDRA-8875:
----------------------------------------
Component/s: Streaming and Messaging
> Add flags field to messages and serialized objects
> --------------------------------------------------
>
> Key: CASSANDRA-8875
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8875
> Project: Cassandra
> Issue Type: Improvement
> Components: Streaming and Messaging
> Reporter: Tyler Hobbs
> Priority: Major
> Fix For: 4.x
>
>
> Currently, we don't have a good way to change add fields to serialized
> objects/commands/messages within a major version, because our logic is based
> entirely on the messaging version (which is only change with major releases).
> Occasionally, this makes it very difficult to fix a bug in a minor version
> release. Some recent example of this include CASSANDRA-8502, CASSANDRA-8087,
> and CASSANDRA-8490, although I'm sure there are more.
> We can take some preventative measures by adding a flags field to serialized
> objects and messages for 3.0, even if we don't have any flags to use yet.
> This will allow us to easily alter behavior or include additional data in a
> minor release without compatibility concerns.
