---------------------------------------
Assignee: (was: Matthias J. Sax)
> Global thread should honor shutdown signal during bootstrapping
> ---------------------------------------------------------------
>
> Key: KAFKA-10317
> URL: https://issues.apache.org/jira/browse/KAFKA-10317
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Matthias J. Sax
> Priority: Major
>
> During startup, the global thread will bootstrap all global stores before it
> enters its main store-update-loop. The store-update-loop exits, when
> `KafkaStreams#close()` is called.
> However, during the bootstrap phase there is no check if
> `KafkaStreams#close()` was called. And thus, KafkaStreams cannot be stopped
> during bootstrapping (ie, the bootstrapping cannot be interrupted).
> To make Kafka Streams more responsive, we should check if `close()` was
> called during bootstrapping, too.
> Note, that `KafkaStreams#start()` actually blocks during bootstrapping atm
> (cf KAFKA-7380) and thus we should fix both issue at once if possible.
