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

如果您将远程缓存存储配置为共享，则无法预加载数据。在您的配置中为 shared="true" 换句话说，您必须设置 preload="false"。

共享远程缓存容器

每个远程缓存存储都会创建一个专用的远程缓存管理器。如果有多个远程存储连接到同一服务器，则这会浪费资源。使用 remote-cache-containers 配置创建共享远程缓存管理器，并使用 remote-store 定义中的名称来引用它们。

提示

如果只有一个 remote-cache-container，则默认在所有远程缓存存储中使用它，但不明确指定一个。

分段

RemoteStore 支持分段，并可按网段发布密钥和证书，从而使批量操作更高效。但是，分段仅适用于 Data Grid Hot Rod 协议版本 2.3 或更高版本。

警告

当您为 RemoteStore 启用分段时，会使用您在 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 不同的片段数，则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。
