Hi, I'm using ThetaSketches in my Spark application. I started by following the outline described in the [Example of using ThetaSketch in Spark](https://datasketches.apache.org/docs/Theta/ThetaSparkExample.html) documentation. Sketches become serializable through Java's `ObjectInputStream` and `ObjectOutputStream`. But since this is also used by Spark for its own serialization/deserialization (during shuffling, etc) I am hitting the size limit for the stream. The [limit is 2GB](https://github.com/frohoff/jdk8u-jdk/blob/master/src/share/classes/java/io/ByteArrayOutputStream.java#L121), and is set by the jdk. I was wondering what other options exist for massively parallelizing Sketches inside Spark apps. Any thoughts, ideas are welcome. Thanks! -- This is an automated message from the Apache Git Service.
