Description

Hello,
I'm using an autocommit consumer, i get some messages, and my SESSION_TIMEOUT_MS_CONFIG is smaller than the total message processing time. In that case, the consumer consume more than one time a message (twice in the log file), how it's possible ? As you can see in the log file, the "msg1" which is in the partition 0 is consume in the same time in the thread : KAFKA-0 and KAFKA-1, however the KAFKA-1 is assigned to the partition 1 not 0.

KAFKA-0,assigned : [vertx_logger-0]
KAFKA-2,assigned : [vertx_logger-2]
KAFKA-1,assigned : [vertx_logger-1]

Can you help me ?
