Migrating Kafka topics without downtime
Each kafka topic defines the number of partitions and replication factors when it’s created. However, once a topic is created, the partition count cannot be changed without affecting the ordering guarantees of the kafka partitions since kafka uses the following formula to calculate which partition a record should go to: partition\_id = partition\_key % number of partitions Kafka partitions are the gateway to concurrency and scalability...
