Cluster management limitations

When managing Kudu clusters, review the following limitations and recommended maximum point-to-point latency and bandwidth values.

  • Rolling restart is not supported.

  • Recommended maximum point-to-point latency within a Kudu cluster is 20 milliseconds.

  • Recommended minimum point-to-point bandwidth within a Kudu cluster is 10 Gbps.

  • If you intend to use the location awareness feature to place tablet servers in different locations, it is recommended that you measure the bandwidth and latency between servers to ensure they fit within the above guidelines.

  • All masters must be started at the same time when the cluster is started for the very first time.
