Description

The 'nchan_redis_publish_msgpacked_max_size' directive is particularly important in configurations where Nchan leverages Redis for message storage and publishing in a pub/sub architecture. When a message is published to Redis using MessagePack serialization, this directive specifies the maximum size, in bytes, that a serialized message can occupy. If a message exceeds this size limit, it will be rejected, ensuring that the buffer sizes in Redis remain manageable and conducive to efficient operation.

Config Example

nchan_redis_publish_msgpacked_max_size 1048576;  # Limits message size to 1MB
⚠

Setting the max size too low may result in valid messages being rejected.

⚠

Care should be taken to ensure the specified size is appropriate for the expected payloads.
