Grant Henke updated KUDU-3115:
------------------------------
Component/s: master
> Improve scalability of Kudu masters
> -----------------------------------
>
> Key: KUDU-3115
> URL: https://issues.apache.org/jira/browse/KUDU-3115
> Project: Kudu
> Issue Type: Improvement
> Components: master
> Reporter: Alexey Serbin
> Priority: Major
>
> Currently, multiple masters in a multi-master Kudu cluster are used only for
> high availability & fault tolerance use cases, but not for sharing the load
> among the available master nodes. For example, Kudu clients detect current
> leader master upon connecting to the cluster and send all their subsequent
> requests to the leader master, so serving many more clients require running
> masters on more powerful nodes. Current design assumes that masters store
> and process the requests for metadata only, but that makes sense only up to
> some limit on the rate of incoming client requests.
> It would be great to achieve better 'horizontal' scalability for Kudu masters.
