What aspect does not occur during the data collection points phase for streaming data?

During the data collection points phase for streaming data, the primary focus is on how data is ingested and managed as it flows into the system.

Ingesting and buffering streaming data are integral components of the data collection process. Buffering provides a way to temporarily hold the streaming data before it is processed or written to the final storage. This allows for smooth handling of incoming data, especially during peak loads or unexpected bursts of activity. Therefore, the aspect of ingesting and buffering is indeed a fundamental part of this phase rather than something that does not occur.

On the other hand, the use of REST APIs for data ingestion, the collection services that pull data from external services, and the integration with messaging services from pub/sub systems, are all recognized methods through which data is gathered and handled during the streaming process. These options highlight distinct methods of obtaining and managing data flow which are appropriate during data collection points.

Thus, the accurate understanding places buffering as a necessary action in the context of streaming data handling rather than an aspect that would not occur in this phase.
