How to serialize all geometry?

[q127981]

如何序列化所有几何？
我添加了自定义的几何图形，希望在spark程序中应用。由于目前不支持自定义几何的序列化，或者说我不知道如何使用FlatBuffers支持序列化我添加的class。导致目前每个spark程序的实例都需要重新构建一次rtree，这样效率很低。我尝试设置Property : spark.serializer=org.apache.spark.serializer.KryoSerializer 修改默认的序列化方式，但是没有作用，甚至很久都没有完成rtree的构建。有没有一种序列化方式，可以不受限制，任意添加自定义几何，且能够完成快速重建rtree？或者我应该怎样使FlatBuffers支持序列化我添加的class?
hi:
I added a custom geometric figure, hoping to apply it in the spark program. Since the serialization of custom geometries is currently not supported, or I don't know how to use FlatBuffers to support serialization of the classes I added. As a result, each instance of the spark program needs to rebuild the rtree, which is very inefficient. I tried to set Property: spark.serializer=org.apache.spark.serializer.KryoSerializer to modify the default serialization method, but it didn't work, and it didn't even complete the construction of rtree for a long time. Is there a serialization method that can add custom geometry without limitation, and can quickly rebuild the rtree?Or how should I make FlatBuffers support serialization of the class I added?

thank you!

Hi, I don't have a quick answer for you on this I'm afraid. Happy to consider suggestions.
