Sean Busbey commented on ACCUMULO-3594:
---------------------------------------
If we went with Avro we could use their maven plugin to generate specific
classes for serialization without needing an external compiler. Alternatively,
we could rely on Avro's generic serialization implementation (but it's a little
slower).
Avro also has good reputation for being "safe", largely because they do
regression testing and favor stability over time. (the disadvantage of this is
that they can be a little slow in adopting new features, but participation in
the community can help mitigate that.)

> We have a number of writable classes, some of which are non-trivial and
> serialized in tables or files:
> * {{org.apache.accumulo.core.tabletserver.log.LogEntry}}
> * {{org.apache.accumulo.core.metadata.schema.DataFileValue}}
> * {{org.apache.accumulo.server.master.state.TServerInstance}}
> Consider converting this (and possibly others) to better message classes to
> easily add more functionality in the future.
