如何通过java查询ignite缓存？

<dependency>
    <groupId>org.apache.ignite</groupId>
    <artifactId>ignite-core</artifactId>
    <version>2.10.0</version>
</dependency>

IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(true);
cfg.setAddresses(Arrays.asList("127.0.0.1:10800")); // 指定Ignite集群节点的IP地址和端口

Ignite ignite = Ignition.start(cfg);

IgniteCache<String, String> cache = ignite.getOrCreateCache("myCache");

String value = cache.get("myKey");

SqlFieldsQuery query = new SqlFieldsQuery("SELECT * FROM myCache WHERE age > ?").setArgs(30);
QueryCursor<List<?>> cursor = cache.query(query);
for (List<?> row : cursor)
    System.out.println(row);
