Hi David
Glad to know that Shoal might meet your clustering needs.
We will work on a formal document covering changes going into 1.1 as
soon as possible.
I have updated the Javadoc for reportJoinedAndReadyState() in
GroupManagementService
<
https://shoal.dev.java.net/nonav/docs/api/com/sun/enterprise/ee/cms/core/GroupManagementService.html>
to better explain the behavioral semantics. This will be captured in
more detail in our wiki page. (I had written a blog entry
<
http://blogs.sun.com/shreedhar/entry/sailfin_drives_a_new_feature>earlier
with the Sailfin driven use case but that does not explain the
functionality in granular detail.)
Among the higher level changes to 1.1 are :
1. Ability to specify a specific NIC address to bind to.
2. Fine tuned state machine wrt health monitoring. Additional
transitional states have now been added to reflect the state of a member
from starting through to stopped/dead.
3. Ability for the application to report its joined and ready state to
service requests. Added api in Join notification signal,
getMemberState() allowing consuming components to query the health state
of a member when a join notification signal is received.
4. Ability to specify a member as a bootstrap node with a URI (specified
on all members) that will allow members to communicate with that member
as a software router when no multicast is available or when the members
are across subnets.
5. Ability for each member to participate in multiple groups.
6. Better resilience in health monitoring with respect to network
issues, and hardware failures.
7. Fixes for a number of bugs reported in Shoal, GlassFish, and Sailfin
projects.
Let us know if you have any other specific questions.
