Обладает ли топик Kafka свойством FIFO (First In, First Out)?

A Kafka topic does not guarantee the global FIFO (First In, First Out) property for all messages, but it ensures order within each partition.

Explanation:

• The topic is divided into multiple partitions.
• Within a single partition, messages are ordered and consumed in the same order they were written.
• However, the order of messages across different partitions is not guaranteed.

If strict FIFO for all messages is important, you should use a single partition, but this will limit scalability and performance.

In summary:

• FIFO is guaranteed at the partition level.
• There is no FIFO for the entire topic if multiple partitions are used.

This allows balancing between performance and message order.
