A polling approach that changes request timing or window size based on observed runtime conditions. In security integrations, adaptive polling helps keep ingestion current while balancing memory use, API quota pressure, and step completion time across different connectors.
What Adaptive Polling Does
Adaptive polling is a timing strategy, not a fixed interval. It adjusts when and how much it asks for based on what the system is seeing at runtime, so ingestion can stay current without overloading the connector or wasting quota.
Where Adaptive Polling Fits in Security Integrations
In practice, adaptive polling sits between source systems and the security platform that consumes their data. It is useful when event volume is uneven, source latency changes, or the connector must balance freshness against resource limits.
The main value is control of backpressure. When the source is quiet, the poller can slow down and reduce unnecessary requests. When activity rises, it can shorten the wait or expand the window so changes are collected faster.
Operational Trade-Offs
Adaptive polling usually improves efficiency, but it also introduces tuning complexity. The implementation has to decide which signals matter, how fast to react, and whether a wider window risks duplicate reads or delayed completion of a batch.
Because the timing logic responds to observed conditions, it can behave differently across connectors or tenants. That makes it a practical choice for heterogeneous environments, but it also means the polling policy should be understood as part of the ingestion design, not just a transport detail.
Why It Matters for Connector Reliability
Adaptive polling is often chosen when the platform needs to protect memory, stay within API quotas, and keep workflow steps from timing out. Those constraints become more important as ingestion scales across many sources with different response patterns.
It is also a resilience mechanism. If one source slows down or becomes bursty, a rigid schedule can either miss useful changes or create avoidable load. Adaptive polling helps the integration adjust without needing manual interval changes every time conditions shift.
