jena的fuseki与tdb2.tdbloader不兼容吗？

Question

我有一个要求，每天增量更新tdb文件。因此，我使用tdb2.tdbloader来完成生成的N-Triples文件。但是当作业完成时，包含tdb数据的数据目录有一个新目录，名为" data -0001“或更多。当我重新启动fuseki服务器时，它给出了这个异常：

我的问题是:我如何在tdb2.tdbloader中使用fuseki，更重要的是，如果我每天更新，那么data文件夹中的目录是否每天都在增加？有没有办法让我把它们合并？

Answer 1

我知道问题出在哪里: tdb2.xxx只能在tdb2上运行。我在fuseki中的配置是tdb1，而不是tdb2。

顺便说一句，tdb2.tdbloader不支持数据集的增量更新。它只是在旧的基础上增加了spo。
