Hi All, I have a question regarding ordering of consumed messages. We timestamp our messages and send them into Kafka in order. I wrote a simple consumer that simply consumes the messages and prints out the timestamp. I see messages for all seven days worth of date being consumed at once.
Our setup: Kafka 0.8 5 Kafka brokers 1400 partitions The consumer has 10 threads, simply connects, consumes and prints timestamps. It is set to the "smallest" offset so that it reads from the beginning. There are many millions of messages so I think I can rule out some partitions not having messages for certain days as the cause. I know that Kafka doesn't guarantee ordering across partitions but I would assume that with this volume of messages I would see the timestamps for the first day, followed by the second day, etc. Instead I see them all print at once. Any ideas what I might be doing wrong?
