Timeouts and Retries

Configure timeouts and retries to handle transient failures and ensure reliable service communication.

Timeout Configuration

defaultTrafficPolicy:
  timeout:
    tcp:
      connectTimeout: "10s"
    http:
      connectionIdleTimeout: "60s"
      maxConnectionDuration: "300s"
      requestTimeout: "30s"

Setting	Description
connectTimeout	Time to establish connection
requestTimeout	Maximum time for complete request
connectionIdleTimeout	Idle connection timeout

Retry Policy

defaultTrafficPolicy:
  retry:
    numRetries: 3
    perTryTimeout: "5s"
    retryOn:
      - "5xx"
      - "connect-failure"
      - "reset"

Retry Conditions

Condition	Description
5xx	Retry on 5xx server errors
connect-failure	Retry on connection failures
reset	Retry on connection resets
retriable-4xx	Retry on retriable 4xx errors

Best Practices

• Set perTryTimeout shorter than total timeout
• Use exponential backoff (handled automatically)
• Limit retries for non-idempotent requests
• Combine with circuit breakers to prevent cascade failures
