aikarajoin
Aikarajoin is a term that may be used to describe a time-bounded join operation in database and data processing contexts. The exact usage varies, and it is not a standardized term in mainstream database literature. Broadly, aikarajoin refers to joining two datasets by aligning records that are related in time, subject to a defined time window or temporal rule. In a typical aikarajoin, records from two sources are paired only if their timestamps fall within a specified interval. This can take the form of a fixed window (for example, join records whose timestamps differ by at most five seconds) or a rolling window that advances with time. Implementations may support exact timestamp matches, tolerance-based joins, or more complex temporal relationships such as interval containment or overlap.
Data models for aikarajoin often involve temporal attributes and time zones. In streaming contexts, aikarajoin is
In English-language literature the concept is usually described as a time-window join or temporal join; aikarajoin
