## Broker profile
|
|
|
|
### Kafka
|
|
|
|
```yaml
|
|
messaging:

|
|

|

bootstrap-servers: [broker-1:9093, broker-2:9093]
|
|
enable-idempotence: true # stable에서 필수
|
|

|
|
max-in-flight-requests-per-connection: 5 # 최대 5

|
|

|
|
tls-enabled: true # production 필수
|
|
authentication-enabled: true # production 필수
|
|
```
|
|
|
|
### RabbitMQ
|
|
|
|
```yaml
|
|
messaging:
|
|
brokers:
|
|
rabbit-primary:
|
|
type: rabbitmq
|
|
stable: true
|
|
production: true
|
|
addresses: [rabbit-1:5671]
|
|
publisher-confirms: true # stable에서 필수
|
|

|
|

|
|

|
|
quorum-queues: true # durable work queue 필수
|
|
tls-enabled: true
|
|
authentication-enabled: true
|
|
```
|
|
|
|
## 보안
|
|
|
|
```yaml
|
|
messaging:
|
|
security:
|
|
kafka-primary:
|
|
producer: { type: SASL_SCRAM, credential-id: kafka-producer }
|
|
consumer: { type: SASL_SCRAM, credential-id: kafka-consumer }
|
|
# admin은 application runtime에 설정하지 않는다
|
|
hostname-verification: true
|
|
access:
|
|
publishable: [order-events]
|
|
consumable: []
|
|
administrable: []
|
|
```
|
|
|
|
## Experimental / Optional
|
|
|
|
기본값은 전부 `false`다.
|
|
|
|
```yaml
|
|
messaging:
|
|
experimental:
|
|
kafka-share: false
|
|
pulsar: false
|
|
nats: false
|
|
bridge:
|
|
spring-cloud-stream: false
|
|
```
|
|
|
|
## Backpressure
|
|
|
|
```yaml
|
|
messaging:
|
|
backpressure:
|
|
global-limit: 512
|
|
per-destination-limit: 64 # global-limit 이하여야 한다
|
|
```
|
|
|
|
`per-destination-limit > global-limit`이면 global limit이 limit이 아니게 되므로 부팅에 실패한다.
