Class CacheContinuousQueryWithTransformerExample

  • public class CacheContinuousQueryWithTransformerExample
extends java.lang.Object
    This example demonstrates how to use continuous queries together with the transformer APIs.

    This API can be used to get a notification about cache data changes. User should provide a custom transformer that will transform change event on a remote node. Result of the transformation will be sent over to a local node over the network. That should lead to better network usage and increase performance in case user select only required fields from a complex cache object.

    Remote nodes should always be started with special configuration file which enables P2P class loading: 'ignite.{sh|bat} examples/config/example-ignite.xml'.

    Alternatively you can run ExampleNodeStartup in another JVM which will start node with examples/config/example-ignite.xml configuration.
