Subject [jira] [Commented] (ACCUMULO-3594) Consider message replacement for Writable classes internally
Date Thu, 19 Feb 2015 21:21:11 GMT


Christopher Tubbs commented on ACCUMULO-3594:

bq. Hadoop also has a version of pb that it uses for its RPC, so that's also a concern to
be aware of for the same reasons.

This might already be a (slight) concern (as in, something to be aware of, not something to
freak out about), since we now have protobuf-generated code in 1.7.0 for replication, and
a new dependency on 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.
