Settings

​

queue_capacity

• Default: 128
• Type: integer; positive

Example 128 gives the queue 128 request slots. When the queue fills, senders must wait rather than keep adding work to memory.

​

max_message_bytes

• Default: 68157440
• Type: integer (bytes); positive

Example 68157440 allows a message up to 65 MiB. A large service response must fit this limit as well as the receiving service’s own response limit.

​

max_connections

• Default: 1024
• Type: integer; positive

Example 1024 permits up to 1024 connections. This counts connections, not the number of requests carried by each connection.

​

Notifications

​

notifications.queue_capacity

• Default: 8
• Type: integer; positive

Example 8 gives the queue eight message slots. The queue’s byte limit still applies when fewer than eight large messages are waiting.

​

notifications.max_message_bytes

• Default: 65536
• Type: integer (bytes); positive

Example 65536 allows a notification up to 64 KiB. Notifications use this smaller limit rather than the main service-message limit.

​

notifications.max_queue_bytes

• Default: 262144
• Type: integer (bytes); positive

Example 262144 gives the queue a 256 KiB total budget. Four 64 KiB messages can fill that budget before the eight-message count limit is reached.
