Message Queueing
Message queueing is a communication method that allows different components of a trading system to exchange information asynchronously. By placing messages in a queue, a system can handle bursts of activity without overwhelming the downstream components.
This is crucial in trading systems where market data ingestion must not be blocked by order execution processes. Effective queueing strategies ensure that the system remains responsive and that no critical data is lost during high-volume events.
It is a fundamental pattern for building decoupled and resilient software architectures. It allows for better load distribution across system components.
