cpu_quota_concurrency specifies the maximum concurrency allowed for each CPU quota of a tenant.
| Parameter | Description |
|---|---|
| Type | Double-precision floating-point number |
| Default value | 4 |
| Value range | [1, 10] |
| Effective upon restart of OBServer node | No |
The number of threads that can be concurrently handled by a tenant is controlled by two parameters: cpu_quota_concurrency and workers_per_cpu_quota. The two parameters must meet the following condition:
workers_per_cpu_quota > cpu_quota_concurrency
workers_per_cpu_quotaspecifies the maximum number of worker threads that a tenant can allocate to each CPU.For more information about workers_per_cpu_quota, see workers_per_cpu_quota.
cpu_quota_concurrencyspecifies the number of active worker threads of the tenant on each CPU, that is, the number of concurrent worker threads.Notice
We recommend that you do not modify this parameter to avoid potential risks. That is, a smaller value may impact performance and even pose stability risks, while a larger value might result in increased memory usage and potential high CPU load.
