Hi Team,
As I am new contributing Kafka project, though I use Kafka before. While I was looking at this Jira issue. I found following list of classes are prominent. KAFKA-18498 <https://issues.apache.org/jira/browse/KAFKA-18498>Kafka Streams main thread does not release lock I am curious and I would like to know the purpose of this classes, which class calling other class and how this 6 class interact each other. Any hierarchic structure? Would anyone explain in briefly? Appreciated. List of Classes: streams/src/main/java/org/apache/kafka/streams/KafkaStreams.java streams/src/main/java/org/apache/kafka/streams/processor/internals/ProcessorStateManager.java streams/src/main/java/org/apache/kafka/streams/processor/internals/StandbyTask.java streams/src/main/java/org/apache/kafka/streams/processor/internals/AbstractTask.java streams/src/main/java/org/apache/kafka/streams/processor/internals/StateDirectory.java streams/src/main/java/org/apache/kafka/streams/processor/internals/TaskManager.java -- Thanks, Swikar
