Robert Stupp updated CASSANDRA-7370:
------------------------------------
Attachment: 7370-v1-prototype.diff
Attached a prototype patch.
* creates new table {{system.host_config}} that contains all fields of
{{Config}}
* inserts new row upon node startup
* inserts new row when one of the setters in {{DatabaseDescriptor}} is invoked
Would be glad to get some feedback :)
> Create a new system table "node_config" to load cassandra.yaml config data.

> Currently the node configuration information specified in cassandra.yaml can
> only be viewed via JMX or by looking at the file on individual machines.
> As an administrator, it would be extremely useful to be able to execute
> queries like the following example;
> select concurrent_reads from system.node_config;
> which will list all the concurrent_reads value from all of the nodes in a
> cluster.
> This will require a new table in the system keyspace and the data to be
> loaded (if required) during the bootstrap, and updated when MBeans attribute
> value updates are performed. The data from other nodes in the cluster is also
> required in the table.
