--------------------------------------
Summary: 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: Core
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
Fix For: 3.0
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.
