--------------------------------
implementation: https://gerrit.cloudera.org/#/c/17273/
> Total table size quota management for every user
> ------------------------------------------------
>
> Key: KUDU-3223
> URL: https://issues.apache.org/jira/browse/KUDU-3223
> Project: Kudu
> Issue Type: Wish
> Reporter: Redriver
> Priority: Major
>
> *Requirement description*
> In production environment, the quota management for total tables size and
> single table size of a single user is necessary. If the quota is reached, the
> write operation including insert and update is forbidden, only table
> creation, scan and delete are allowed.
> We need to allow admin to configure the quota for every user, monitor the
> quota status, and stop the write operation with an error returned to client.
> So, I hope Kudu cli can list the status. Currently, the kudu table statistics
> only gives the disk size and live row count. It is better improve this by
> adding user name for table statistics, or create a new parameter to query
> every table size for every user, and disable/enable a user's write privilege.
> Can this be configured through Apache Ranger?
> *Typical scenarios*
> # Some user has malicious operation to create a huge table, or many small
> tables, as a result, the total table size exceeds the cluster's capacity, we
> have to stop him in time.
> # When writing Kudu table through Flink, the streaming process is always
> running, which means the Kudu table writing never stopped. If we do not have
> a protection, the Kudu cluster will be exhausted someday.
