Programmatic configuration

As we saw within the book, it is also possible to configure Hazelcast programmatically, this can provide for a higher application control of the cluster.

Set general properties

Config conf = new Config();
 conf.setProperty("hazelcast.map.partition.count", "271");

Set instance name

conf.setInstanceName("my-instance");

Set as lite member

conf.setLiteMember(true);

Get reference to map configuration

MapConfig citiesConf = conf.getMapConfig("cities");

Modify default behavior

citiesConf.setBackupCount(2);
citiesConf.setAsyncBackupCount(1);

Add map index

citiesConf.addMapIndexConfig(
  new MapIndexConfig("country", false));
