Rick Hillegas commented on DERBY-3501:
--------------------------------------
Thanks for the great spec, Francois. I have some comments:
o It would be nice to have TOC entries for the following sections: Assumptions,
Requirements, Replication MBean, and Attributes.
o There's a Javadoc entry in the TOC but no corresponding section further down.
o I would recommend changing the names of some of the attributes:
- Master attributes:
HostName -> SlaveHostName
PortNumber -> SlavePortNumber
LastInstant -> LastLogInstant
LastShipped -> LastLogChunkShipped
- Slave attributes:
HostName -> MasterHostName
LastInstant -> LastLogInstant
LastReceived -> LastLogChunkReceived
o In "JMX Client API and ReplicationMBean Access", did you intend for the last
line of the first code block to appear in a bigger font and to be split off
from the previous line?
o Could you give us an example of how to use the ping feature?
o I agree that writing a VisualVM plugin for Derby would be very useful. You
may have some idea of how hard that is--I don't! I don't know what the
licensing issues are for such a plugin so I can't say whether this work is even
possible for our Apache community. Provided that there are no intractable
licensing issues, I think that this work falls inside the Derby charter--but
other community members may have other opinions.
o Public API - The existing MBeans are documented in our public api in the
org.apache.derby.mbeans package. I think that we should document this new MBean
there too.
