Static polling is a communication method where a client or system repeatedly queries a server or data source at fixed, predetermined intervals to check for new information or status updates. This approach maintains data synchronization by regularly pulling data, regardless of whether changes have occurred. In crypto, it might involve a trading system periodically requesting updated RFQ prices, order book snapshots, or account balances from an exchange API.
Mechanism
The operational logic dictates a cyclical request-response pattern. A client sends a query to the server, waits for a response, processes it, and then waits for the predefined interval before sending the next query. This continuous, uniform frequency consumes network bandwidth and server resources, as many requests may return identical data if no changes have transpired.
Methodology
The strategic consideration for static polling balances the need for data freshness against resource consumption. While simpler to implement than event-driven alternatives, its inefficiency in dynamic environments can introduce unnecessary latency or overload systems. For institutional crypto operations, its use is typically restricted to less time-sensitive data requirements, with more advanced real-time communication protocols preferred for RFQ execution and high-frequency trading.
