Kafka - Multiple producers writing to same topic and order of message is important

Question

Let us say there are two Producers P1 and P2.
P1 makes attempt to write log L1 at time t1 to a partition PT however it gets written at t2 due to network latency.
P2 makes attempt to write log L2 at time t3 to a partition PT however it gets written at t4 due to network latency.

Let us say t1<t3 however t2>t4 so what will be the final order of L1 and L2 in the partition PT?

Answer 1

Yes, if both producers are writing to the same Partition, the order of the messages will be the order of reception of those messages, regardless of when the Producer send the message.
