Meaning
Direct transmissions provide a chronological sequence of every bid, win and interaction occurring within a programmatic environment. The raw event stream contains unaggregated data that has not yet been processed into a higher level report or dashboard summary. It acts as the ultimate source of truth for high volume media buying systems.
Technical Processing
Input data arrives as a constant flow of encoded tokens from diverse geographic nodes across the network. A raw event stream is essentially unusable for humans without the use of high speed filtering and visualization tools. It allows data scientists to look for anomalies or performance trends that summary tables often obscure.
Because the format is basic text or simple integers, it can be ported between different analytical programs without translation issues.
Data Ownership
Corporate policies define who maintains the history of this sequence after the campaign ends. Holding a raw event stream gives a company more independence because it allows them to calculate their own results without relying on a vendor’s prepackaged metrics. Storage costs remain high because of the sheer quantity of separate data points produced every day.
Firms typically purge these files every few months to save server space once the key insights are recorded.
Retention Barrier
Systems stop recording the specific interaction once the retention window of the local node expires. This raw event stream closes off for older entries to prioritize the ingestion of the upcoming millions of events. Final storage of summaries replaces the granular file over time.
