Or is this the correct way of setting compound format?

gistfile1.java

Settings settings = settingsBuilder()
                .put("gateway.type", "local")
                .put("index.number_of_shards", 1)
                .put("index.compound_format", true)  // ##### Here ?
                .build();
                
Node node = NodeBuilder.nodeBuilder()
                .settings(settings)
                .local(true)
                .node();
 
Client client = node.client();
 
client.admin().indices()
    .prepareCreate("myindex")
    .setSettings(settingsBuilder().put("index.compound_format", true).build()) // ##### Trying also here
    .execute().actionGet();
