ApacheIgnite-通过sql驱动程序查询缓存

我在Ignite中创建了一个缓存，现在我正试图通过Ignite包中提供的sqlline查询它。在文档中，它只讨论创建表、索引、查询这些表等。。但是关于查询通过

ignite.getOrCreateCache（）

以这种方式创建的缓存没有任何内容。鉴于ignite功能丰富，我认为这是可能的

我错过了什么

笔记：

• 点火版本=2.3.0
• 在我的代码中，通过ignite Sql机制的SqlFieldsQuery运行良好
• 这看起来非常类似于，但我的发行版只有一个h2-jar，h2-1.4.196.jar，尽管我使用的是springboot

创建缓存的java代码

我终于明白了。让我找到了答案。架构名和表需要按h2 db引用

以下是语法：

以下是连接到Ignite中特定架构的几个选项：

jdbc:ignite:thin://172.16.0.5/mySchema -将连接到“MYSCHEMA”（不区分大小写）

jdbc:ignite:thin://172.16.0.5/“mySchema”-将连接到“mySchema”（区分大小写）

cacheConfig.setName("eventCache");
cacheConfig.setTypes(TenantKey.class, EventCachePojo.class);
cacheConfig.setIndexedTypes(TenantKey.class, EventCachePojo.class);
Cache<String, EventCachePojo> cache = ignite.getOrCreateCache(cacheConfig);
