{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Question \u003e How Kafka partitions are managed by Axon","articleBody":"Currently it seems there is no documentation on how Kafka partitions are managed Axon.\r\n\r\nExample of questions:\r\n- what is the strategy to assign an event to a Kafka partition inside a topic (producer side)? How to override this? Is it advised to override this?\r\n- Where does Axon store the offset for a given partition? Does it uses Kafka in order to store the offsets or does it store it internally?\r\n- How are Kafka partitions related to Axon segments?\r\n- Is it possible to have a dynamic number of segments? I would like the number of segments to be automatically aligned with the number of partitions.\r\n- How is this related to the SequencingPolicy? Is the result of the SequencingPolicy used in order to assign a message to a partition?\r\n- How are segments assigned to node? It is written in the documentation that nodes compete for segments. Are the segments automatically rebalanced when new node join the group?\r\n- How to increase the number of segments after it has been defined? (create new tracking event processor with a different initialSegmentCount?)\r\n\r\nCould you please provide some insight on this? Would be nice to have a paragraph in the documentation explaining the general integration of Axon with Kafka.","author":{"url":"https://github.com/ghilainm","@type":"Person","name":"ghilainm"},"datePublished":"2018-08-16T15:20:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/86/ReferenceGuide/issues/86"}
