what: Pool of pre-provisioned ADB-S resources that multiple databases share.
|
|
Reduces provisioning time and allows resource sharing across databases.
|
|
|
|
when_to_use:
|
|
- Many small databases (SaaS per-tenant model)
|
|
- Need fast provisioning (<1 minute vs 2-5 minutes for standard ADB-S)
|
|
- Workloads with staggered peak times across databases
|
|
- Dev/test environments with many short-lived databases
|
|
|
|
when_NOT_to_use:
|
|
- Single large database (just use ADB-S directly)
|
|
- All databases peak simultaneously (no benefit from pooling)
|
|
- Need strict resource isolation between databases
|
|
|

max_ocpu_per_pool: 512

pool_ocpu_payg: "Per OCPU per hour for the pool"
|
|
notes:
|
|
- "Pool resources are billed whether databases use them or not"
|
|
- "Individual databases draw from the pool allocation"
|
|
- "Cost-effective when average utilization across pool is >50%"

|
gotchas:
|
|
- id: EP-001
|
|
issue: "Pool resources are committed even when idle"
|
|
impact: "Under-utilized pools cost more than individual ADB-S instances"
|
|
recommendation: "Size pool for aggregate average, not sum of peaks"
|
|
- id: EP-002
|
|
issue: "Noisy neighbor risk within pool"
|
|
impact: "One database can consume disproportionate resources"
|
|
recommendation: "Set per-database OCPU limits to prevent resource hogging"
