Polling is when a system actively queries each data source at fixed intervals for updates; compared with event-driven real-time push, it is simpler to implement but has latency, and frequent queries consume considerable compute.

UnverifiedThe primary factor in deciding whether data suits real-time querying or pre-ingestion is the data change frequency; SEC filings update quarterly and Census data is released annually, making them suitable for pre-ingestion, while Wikipedia entries may be edited hourly and are better suited to real-time querying.79% similarUnverifiedMirroring manual messages into the application database has high real-time performance but requires handling message ordering, duplicates, and state write-back; maintaining a separate audit stream suits compliance and debugging but offers a poor query experience; periodic reconciliation is simple to implement but has a delay window.74% similarUnverifiedIn real-time monitoring and metrics systems, two-stack aggregation allows rolling metrics such as "the number of requests in the last N seconds" and "the P99 latency in the last N seconds" to be updated incrementally as data arrives, rather than rescanning the window each time.71% similar
