6.13. 远程缓存存储

远程缓存存储 RemoteStore，使用 Hot Rod 协议在 Data Grid 集群上存储数据。

注意

如果将远程缓存存储配置为共享，则无法预加载数据。换句话说，如果在配置中 shared="true"，那么您必须设置 preload="false "。

分段

RemoteStore 支持分段，并可按网段发布密钥和条目，从而提高了批量操作的效率。但是，分段仅通过 Data Grid Hot Rod 协议版本 2.3 或更高版本提供。

警告

当您为 RemoteStore 启用分段时，它使用您在 Data Grid 服务器配置中定义的片段数量。

如果源缓存被分段并使用与 RemoteStore 不同的片段，则会为批量操作返回不正确的值。在这种情况下，您应该禁用 RemoteStore 的分段。
