type QuotaCenter 

type QuotaCenter struct {
	// contains filtered or unexported fields
}

QuotaCenter manages the quota and limitations of the whole cluster, it receives metrics info from DataNodes, QueryNodes and Proxies, and notifies Proxies to limit rate of requests from clients or reject all requests when the cluster met resources issues. Limitations:

  1. DML throughput limitation;
  2. DDL, DQL qps/rps limitation;

Protections:

  1. TT protection -> dqlRate = maxDQLRate * (maxDelay - ttDelay) / maxDelay
  2. Memory protection -> dmlRate = maxDMLRate * (highMem - curMem) / (highMem - lowMem)
  3. Disk quota protection -> force deny writing if exceeded
  4. DQL Queue length protection -> dqlRate = curDQLRate * CoolOffSpeed
  5. DQL queue latency protection -> dqlRate = curDQLRate * CoolOffSpeed
  6. Search result protection -> searchRate = curSearchRate * CoolOffSpeed
  7. GrowingSegsSize protection -> dmlRate = maxDMLRate * (high - cur) / (high - low)

If necessary, user can also manually force to deny RW requests.
