Tenant Resource Isolation with Resource Groups

Multi-tenant clusters share OBServer processes. Without isolation, a batch job on tenant A can starve OLTP on tenant B.

Resource groups

Define groups mapping to CPU shares and IOPS limits:

CREATE RESOURCE GROUP olap_group
  MAX_CPU = 30, MIN_CPU = 10;

CREATE RESOURCE GROUP oltp_group
  MAX_CPU = 70, MIN_CPU = 40;

Bind users or sessions:

SET RESOURCE_GROUP = 'oltp_group';

Noisy neighbor signals

Watch tenant_cpu_usage, long-running sessions, and memstore freeze events per tenant in OCP.

Testing

Run OLAP extract concurrently with sysbench on another tenant. Verify OLTP p99 stays within SLA when groups are configured vs. default shared pool.
