Hi, I'm not sure where to put this, but I've found a typo on a page Caching: "
- *Serialization:* The default serialization in Spark is Java serialization. However for better peformance, we recommend Kyro serialization, which you can learn more about here <https://spark.apache.org/docs/latest/tuning.html#data-serialization> " It has to be "Kryo". Hope, this helps. -- Be well! Jean Morozov
