I'd like to introduce new feature for kafka client: Making org.apache.kafka.clients.Metadata#TOPIC_EXPIRY_MS configurable The problem is: if application sends records to some topic rarely then topic metadata gets expired and sending thread is blocked by waiting topic metadata. Easy fix of this exact problem is to make Metadata#TOPIC_EXPIRY_MS configurable and set it value higher than record sending period. -- Pavel +7-903-258-5544 skype://pavel.moukhataev
