Abstract
Aspects of the disclosure relate generally to a distributed event joining system for joining primary and secondary events based on a common key. In one example, a continuous stream of primary events may be stored at a cache layer. Each primary event may be associated with a primary event key which may be used to generate an index map for the cache layer. After a time T, the stream of primary events may be sent to long term memory. The system may also receive secondary events, each associated with a primary key. The primary key may be used to identify a primary event in the cache layer. If the primary event is not available in the cache layer, the long term memory may be searched for the primary key. Paired events may then be submitted to a distributed joined event storage system.
