Question

我要求每天增量更新tdb文件。所以我使用tdb2.tdbloader来生成生成的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名为＆＃34; data-0001＆＃34;的新目录。或者。当我重新启动fuseki服务器时，它给了我这个例外：

我的问题是：如何将fuseki与tdb2.tdbloader一起使用，更重要的是，如果我每天都进行更新，那么数据文件夹中的目录是否每天都在增加？无论如何，我有合并它们吗？

Answer 1

我知道问题是什么：tdb2.xxx仅适用于tdb2。而我在fuseki中的配置是tdb1而不是tdb2。

顺便说一句，tdb2.tdbloader不支持对数据集进行增量更新。它只会添加旧的。

jena的fuseki与tdb2.tdbloader无法兼容吗？
