Apache Spark already has two official APIs for JVM – Scala and Java – but we’re hoping the Kotlin API will be useful as well, as we’ve introduced several unique features. This section is about what’s in the works for technologies that you may want to keep on your radar. Articles This section is about inspiration. Cassandra 4.0

Initially we somewhat naively assigned very large heaps to the Java virtual machine (JVM). Additionally, we would recommend reviewing the memory management section of Confluent’s Kafka Streams documentation as customising the RocksDB configuration was necessary in some of our use cases.

If you are already using a JVM stack, while Java has some support for FP, there are JVM languages with much better support for it that can be integrated with existing Java code, like Scala, Kotlin or Clojure. You describe the computation in a lazy way and run it at the very end, making it extremely composable.
