Indexing RavenDB空间索引未建立

我已经成功地将geodata导入到一个名为AdministrativeArea的类中，其中包括一个WKT字段。此字段包含长度和纬度的多边形坐标点。我已将其声明为字符串。 我想查询文档，找出给定边框中包含哪些多边形/地理区域。为此，我使用空间特征创建了一个索引。 这个索引或我构建它的方式似乎有点“关闭”：要么索引计数停留在0上，什么也没有发生，要么它开始构建，但停留在一个随机数上，我收到一条错误消息。有人能帮忙吗

谢谢

代码/错误消息：

…和一个JSON示例（其中约有260.000个…）

顺便说一句：在260.000个区域中，每个区域内都有数百个（如果不是数千个的话）lat/lng点（出于空间原因，我在上面的示例中截断了大约90%的坐标…）。也许我的方法不适合这个案子

RavenDB索引行为在这方面非常奇怪：它似乎在索引任务上“卡住了”（CPU在20%到40美元之间，RAM消耗持续但缓慢地增加），但没有创建新的索引项，也没有出现错误消息。我在一台16GB内存的笔记本电脑和一台~3.6GHz的i7上运行这个

这就是你的形状

问题是这个形状长约5公里，宽600-700米，而且没有很好地对齐。 我们的默认精度模式设置为5米左右，这意味着我们需要有效地绘制一个由许多5米小片组成的形状，粗略估计大约为350K

要么简化形状，要么降低精度

您可以在这里看到关于空间精度的文档：

请将完整数据发布到您的实际文档中。@Ayendrahien我已经更新了描述。好吧，也许我严重低估了这个地理数据索引任务的计算资源需求：它确实在进展，但速度慢得令人难以置信。我想这是可以理解的，因为它必须为数百万个lat lng坐标点构建一个散列（它实际上就是这样做的吗？）@AyendeRahien你有没有任何-甚至是远程-可比的性能统计数据，这样我就可以知道如何解决这个问题了？如果答案是：你的笔记本电脑需要2个月的时间，我必须考虑其他选项：-谢谢你的澄清。我开始明白这里到底需要多少计算。260.000个地理区域，由350.000个5m块组成。但至少我现在明白了背后的动力。形状“奇怪”的原因是，为了简洁起见，我特意“剪裁”了所有其他点，以便在stackoverflow上发布。最后两个问题：1）有没有办法告诉RavenDB当前的计算结果（日志？=>“（…）导致索引xyz给定文档（…）”）2）当我暂停并恢复索引时，它会丢失任何东西不，恐怕它不会报告它在单个索引项中所做的工作。是的，暂停/恢复将重置该文档的所有内容
