Kryo Serializer

by Peter Veentjer — Oct 16, 2013

A week ago I was called in to help a large online webshop with a problem.

The problem was that they could not keep enough products […]

In-Memory Format

by Peter Veentjer — Sep 21, 2013

When a value is stored in a normal HashMap, the actual instance is stored. This works fine because the HashMap is not a distributed data-structure and therefor everything can be done in the same memory space. The Hazelcast IMap is distributed data-structure, so storing a value created one one machine and reading it on a […]

by Fuad Malikov — Sep 5, 2013

XML Variables

by Peter Veentjer — Aug 14, 2013

One of the new features in Hazelcast 3.0 are XML variables which provided a lot of flexibility for Hazelcast xml based configuration. Imagine that you have the following configuration: <hazelcast> <group> <name>group1</name> <password>password1</password> </group> </hazelcast> As you can see the group name and password are hard coded. Apart from being a potential security risk it […]

User Context

by Peter Veentjer — Aug 2, 2013

One of the new features of Hazelcast 3 is the ability to pass user-context to a HazelcastInstance. This is very useful if you need to access dependencies, but only have a HazelcastInstance available.

Importan note: This blog post have been updated to reflect recent changes in Hazelcast API. Hazelcast relies heavily on serialization.

What’s new in Hazelcast 3?

by Fuad Malikov — Jun 3, 2013

As Hazelcast grew with more and more features, we often felt that the inner architecture is no longer good enough to support those additions. It was almost impossible to introduce some of new features that community really wanted. So a decision made […]
