-----------------------------------------
Summary: Message Accumulation in case of no connection to Kafka
Key: KAFKA-6909
URL: https://issues.apache.org/jira/browse/KAFKA-6909
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Alexander Stepanov
Simple situation:
0) We have service A which works with Kafka as client
1) No connection to Kafka
2) Service A accumulates messages for sending to Kafka, but still no connection
to Kafka
3) Then service A is crashed for some reason, for example, OOM or just server
is dead
4) How to recover accumulated messages?
I think - it will be good to have some general code basement to persist
service's outgoing messages to Kafka. For example, if service A is crashed, it
can fetch messages from some local storage on startup and resend it to Kafka.
