Michael Miller commented on ACCUMULO-4050:
------------------------------------------
Notes from design discussion...
This change would create:
- hierarchy of configuration containers (provided by the
ServerConfigurationFactory)
- Zookeeper observers will update the containers reference to the snapshot
- Access to the configuration will require a call to getSnapshot on the
configuration container
A call to getSnapshot on the configuration container returns a hierarchy of
immutable snapshots to be used by the code. In order to get any updates made to
the configuration, the code will required another call to getSnapshot.
> Serialize table configs into a single ZK node

> URL: https://issues.apache.org/jira/browse/ACCUMULO-4050
> Project: Accumulo
> Issue Type: Sub-task
> Reporter: Christopher Tubbs
> Assignee: Michael Miller
> Fix For: 2.0.0
>
>
> Use a single ZK node to store table configs, rather than split across
> multiple configs. This should make it easier to implement atomic changes to
> the configuration, and should simplify reading loading/saving configuration
> from/to ZooKeeper.
