Long time, no blogging as I was very busy with version 1.5. I am happy to say that we have a release candidate available for download. From the 1.5 release notes:
Major internal refactoring.
Full implementation of java.util.concurrent.BlockingQueue. Now
queues can have configurable capacity limits.
Super Clients: Members with no storage. If
-Dhazelcast.super.client=true JVM parameter is set, that JVM will join
the cluster as a 'super client' which will not be a 'data partition'
[no data on that node] but will have super fast access to the cluster
just like any regular member does.
Http Session sharing support for Hazelcast Webapp Manager. Different
webapps can share the same sessions.
Ability to separate clusters by creating groups.
java.util.logging support (thanks to Emile V.).
I am testing it on 20-100 servers on Amazon EC2 platform. I plan to
demo '100-node-cluster' live to the world in couple of weeks. How long do you think it takes to get a Hazelcast cluster of 100 nodes up and running on EC2? With the setup I have it is just couple of minutes.
Please test the 1.5-RC1 as much as you can and publish the issues at
http://code.google.com/p/hazelcast/issues/list or email me.
1.5 was a big milestone for Hazelcast so it took awhile. It will be
much faster to add new features from now on. Feature list for 1.6 is
already determined:
Support for synchronous backups and configurable backup-replica-count.
Eviction support. Timed eviction for queues. Pluggable eviction for maps.
Statistics/history for entries. create/update/remove time,
number of reads/updates, first/last read times.
MultiMap implementation. similar to google-collections and
apache-common-collections MultiMap but distributed and thread-safe.
Cluster-wide receive ordering for topics.
Even though we are not done with 1.5, I am already very motivated for
1.6. All other planned features can be found here.
If yours aren't there, put them up or let me know.
If you like to get involved and/or participate in Hazelcast related discussions, send me an email (oztalip@gmail.com) to join Hazelcast Google Group.
Note: What is Amazon EC2 platform? Simply it is a server farm that you
can rent as many server as you want for as long as you need and pay as
much as you used... Since I don't own 100 servers, I do rent them for
hours/days from Amazon. see http://aws.amazon.com/ec2/ for more info.
