This topic introduces the NATs-related configurations of Milvus.
NATS is a message-oriented middleware that allows data exchange between applications and services, segmented in the form of messages. Milvus uses NATS as a underlying engine for reliable storage and pub/sub of message streams. You can use it as an alternative to RocksMQ.
Under this section, you can configure message size, retention time and size, etc.
