Dynamic repartitioning and load sharing

The main objective

Handling the load from multiple clients that potentially can flood specific space

which is highly updated.

GigaSpaces out-of-the box features

• Content-based routing where you control the routing index at the object level

• Template routing that controls the way the templates (which are the listeners of

the continues queries) are routed. In other words you can decide how to route

your template by setting the routing index of the template object. The default is

routing the templates to all partitions.

• SLA driven container by measuring of the memory, CPU, disk utilization. You

can add your own custom SLA watcher / monitoring bean
