Abstract

Java applications retrieve memory items as needed. The function of garbage collection (GC) on Java Virtual Machine (JVM) is to automatically determine which memory is no longer in use by the Java system and to deallocate the objects stored in this part of the memory. As memory is restored to JVM automatically, Java developers are not responsible for explicitly deleting unused memory items. We study the performance of various GCs on an Apache Kafka-Storm platform for processing a real-time workload. We demonstrate that the choice of the Garbage collector is sensitive to the configuration of Kafka and the impact of Garbage Collection events on the latency of processing application.
