Scenario

l Monitoring and troubleshooting: By viewing partition status, you can learn the health and data processing of each partition. If a partition has problems such as latency or data loss, you can detect, troubleshoot and repair it in time.

l Performance optimization: You can view partition status to understand the load and data processing speed of each partition. If a partition is under a high load or has a slow processing speed, you can take appropriate measures to optimize the performance, such as increasing the number of partitions or optimizing the consumption capacity of consumers.

l Capacity planning: By viewing partition status, you can learn the data size and data growth of each partition. Depending on the partition status, you can do capacity planning to ensure that you have enough storage space to store your data at present and in the future.

l Data migration and rebalancing: When data migration or rebalancing is required, viewing partition status can help determine the appropriate migration plan and balancing policy. By learning the status and load of each partition, you can better plan on and execute data migration and rebalancing operations.

l Fault tolerance and redundancy management: By viewing partition status, you can learn the distribution of replicas and data redundancy in each partition. If the number of replicas in a partition is insufficient or unevenly distributed, you can take appropriate measures to improve the fault tolerance and redundancy of data.

In summary, you can view partition status in Kafka in scenarios such as monitoring and troubleshooting, performance optimization, capacity planning, data migration and rebalancing, and fault tolerance and redundancy management to ensure system stability, performance, and reliability.
