Making RTree Serializable

[rahulmidha31]

Hi,

I was trying to integrate this in Spark for one of my use cases. However, post constructing the RTree object I wanted to broadcast it to the executors, but failed since the RTree object was not serializable.

Work around: Initialized it once per executor, but still it would be great if we could simply mark it serializable.

Serialization is supported and is discussed in the README.md.

Thanks David, though i was talking about the default java serialization but found a way to make it work with Spark. Thanks..

Hi,
Can you please describe how did you solve it?
Thanks.

Hi,

For spark, I just added a property for using the default serializer as Kryo.

Property : spark.serializer=org.apache.spark.serializer.KryoSerializer

Hello, may I ask, I also want to use it in spark. But I added custom geometry, how can I serialize it?In addition to adding attributes, what else to do？ thank you! @rahulmidha31
