fuseki - Can I setup two Fuseki instances using the same database directory?

Question

I need to have a public read only instance to query data using the port 3030 and a private read and write instance to add and update data using the port 3031. Both instances are only accessible throw a web server using distinct domains and port 80. Also, the private instance provides access using an HTTP user/password.

My question is about concurrency: Has Fuseki support to concurrently access to a directory database using two server instances?

Answer 1

我在Fuseki 文档中找到了答案：

不支持在多个 JVM 中运行的多个应用程序使用相同的文件数据库。必须有一个 JVM 控制数据库目录和文件。

使用 Fuseki 为多个应用程序提供数据库服务器。Fuseki 支持 SPARQL 查询、SPARQL 更新和 SPARQL 图形存储协议。

因此，答案是不支持使用同一数据库的多个实例。
