Andrew Purtell commented on HBASE-10994:
----------------------------------------

Only tackling quotas, not also reservations, assumed.

>                 Key: HBASE-10994
>                 URL: https://issues.apache.org/jira/browse/HBASE-10994
>             Project: HBase
>          Issue Type: Umbrella
>            Reporter: Matteo Bertozzi
>            Assignee: Matteo Bertozzi
>            Priority: Minor
>              Labels: multitenancy, quota
>
> Currently HBase treats all tables, users, and workloads in the same way.
> This is ok, until multiple users and workloads are applied on the same cluster/table.
Some workloads/users must be prioritized over others, and some other workloads must not impact
others.
> We can separate the problem into three components.
>  * Isolation/Partitioning (Physically split on different machines)
>  * Scheduling (Prioritize small/interactive workloads vs long/batch workloads)
>  * Quotas (Limit a user/table requests/sec or size)
> This is the umbrella jira tracking the multi-tenancy related tasks.
> An initial design document is up for comments here: https://docs.google.com/document/d/1ygIwZpDWQuMPdfcryckic6ODi5DHQkrzXKjmOJodfs0
