使用 Redshift 作为 Pentaho PDI 数据库存储库

Question

我在 PDI CE 7.0 上运行 Spoon 并尝试第一次设置我的数据库存储库。 我可以使用 SQL Server 作为我的数据库存储库，但我想知道是否可以使用我的 Redshift 服务器作为我的数据库存储库。

当我测试我的数据库连接时，它运行良好。 但是，当我尝试连接到存储库时，我收到一条错误消息，提示“您似乎没有连接到服务器。请检查您使用的路径并确保服务器已启动并正在运行” (Click to see error message)

我已经尝试更改我的 JDBC 驱动程序。我已经使用 Postgresql Driver 9.3 和 8.4 以及 Amazon 的 Redshift Driver 进行了测试。通过所有这些选项，我得到了相同的信息。

是否可以使用 Redshift 作为我的数据库存储库？

这是我从 Spoon 控制台收到的堆栈跟踪。

Answer 1

您不应将 Redshift 用作存储库。 Redshift 是一个大型数据仓库，具有面向列的存储，而存储库是一个可操作的数据库，在面向行的存储中效果最好。

话虽如此，您应该查看实际的日志消息（在 Spoon 中，它们将在控制台中）以确定原因。作为第一个猜测，我会检查您是否安装了 JDBC 驱动程序。
