I'm sorry, if I ask my question by the wrong community. What is a difference between Spark ML and Flink ML and between Spark and Flink in general? The both projects are the projects of Apache, I would like to know why Foundation has two similar projects.

PPS This question has been already discussed by Stack Overflow community. The topic is What is the difference between Apache Spark and Apache Flink
