Near real-time refers to data processing and communications that quickly respond to events soon after they occur. Unlike real-time processing, near real-time implies that processing isn't optimized to be as fast as possible. The time involved in near real-time processing depends on the problem space. A delay of minutes, seconds or milliseconds is commonly considered near real-time. The following are illustrative examples.
Background ProcessesA social media platform has a variety of background processes that inspect user generated content for policy violations within a few minutes. In other words, content is posted in real-time but is removed in near real-time if an algorithm decides it violates the firm's policies.
CommunicationsA messaging app usually delivers messages within a few seconds. This can be compared to voice communications that require real-time data or conversations become jumbled.
An ecommerce platform informs a customer support platform of a new order within a minute. It is technically feasible to do the integration in sub-second time but this is deemed unnecessary as customers rarely reach a customer service agent in under a minute.
AnalyticsA web analytics tool allows users to view current traffic to a website with a delay of a few minutes.
