KubeMQ Bridges Queue Target

KubeMQ Bridges Queue target provides a queue sender for processing sources requests.

Prerequisites

The following are required to run the queue target connector:

• kubemq cluster
• kubemq-bridges deployment

Configuration

Queue target connector configuration properties:

Properties Key	Required	Description	Example
address	yes	kubemq server address (gRPC interface)	kubemq-cluster-a-grpc.kubemq.svc.cluster.local:50000
client_id	no	set client id	"client_id"
auth_token	no	set authentication token	JWT token
channels	no	set array of channels values to send the queue message	"queue.a,queue.b,queue.c"
expiration_seconds	no	set default expiration seconds for each queue message	0 - default, no expiration
delay_seconds	no	set default delay seconds for each queue message	0 - default, no delay
max_receive_count	no	set how many failed queue messages before routes to dead-letter queue	0 - default, no routes to dead-letter queue
dead_letter_queue	no	set dead-letter queue	"dead-letter.queue.a"
