Spark Cassandra Connector的作者Russell Spitzer曾经做过一个讲座https://www.youtube.com/watch?v=cKIHRD6kUOc,slides在这里:https://www.slideshare.net/DataStax/maximum-overdrive-tuning-the-spark-cassandra-connector-russell-spitzer-datastax-c-summit-2016
里面有讲到不少调优的窍门,比如:Batching Key,Sorting,Turning off Batching When Beneficial,Having enough Data in a Task。
另外,这个开源项目的参考手册里提到的这些参数可以看一下:https://github.com/datastax/spark-cassandra-connector/blob/master/doc/reference.md#write-tuning-parameters
