Guozhang Wang updated KAFKA-3262: --------------------------------- Labels: user-experience (was: developer-experience) > Make KafkaStreams debugging friendly > ------------------------------------ > > Key: KAFKA-3262 > URL: https://issues.apache.org/jira/browse/KAFKA-3262 > Project: Kafka > Issue Type: Sub-task > Components: streams > Affects Versions: 0.10.0.0 > Reporter: Yasuhiro Matsuda > Labels: user-experience > Fix For: 0.10.1.0 > > > Current KafkaStreams polls records in the same thread as the data processing > thread. This makes debugging user code, as well as KafkaStreams itself, > difficult. When the thread is suspended by the debugger, the next heartbeat > of the consumer tie to the thread won't be send until the thread is resumed. > This often results in missed heartbeats and causes a group rebalance. So it > may will be a completely different context then the thread hits the break > point the next time. > We should consider using separate threads for polling and processing. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
